|-
|| '''Slide Number 1'''
|| Welcome to the Spoken Tutorial on '''Simulation of a SMIB using OpenIPSL.'''
|-
|| '''Slide Number 2 '''

'''Learning Objectives'''
|| In this tutorial, we will learn:* How to '''simulate''' a controlled''' SMIB system'''
* Plotting''' voltage profiles''' of '''buses'''
* Plotting '''delta curve '''of the generator

|-
|| '''Slide Number 3'''

'''System Requirements'''
|| To record this tutorial, I am using* '''OpenModelica Version 1.12.0 '''and
* '''Linux OS 16.04'''

Also use the latest version of OpenIPSL to avoid compatibility issues. I am using OpenIPSL version 1.5.0.

The process demonstrated in this tutorial is identical in other OS also such as-* '''Windows'''
* '''Mac OS X '''or
* '''FOSSEE OS '''on '''ARM'''.

|-
|| '''Slide Number 4'''

'''Prerequisites'''

|| To follow this tutorial, you should have knowledge of:* Power systems
* Modelling using '''OpenModelica'''

For relevant '''OpenModelica '''tutorials, please visit our website.
|-
|| '''Slide Number 5Prerequisites'''
|| Earlier in this series, we have already seen * How to connect a controlled '''SMIB system '''

|-
|| '''Open the SMIB model from the earlier tutorial.'''
|| Let us open the '''SMIB system''' which we modelled in earlier tutorial.

Also open the '''OpenIPSL library.'''
|-
||
|| I have already opened the '''SMIB system'''.
|-
|| '''Shift to network window and drag and drop Generator model onto it'''
|| Now the next task is setting up each component by entering the '''parameter''' '''data''' and '''power flow''' '''data.'''
|-
|| '''Double click on the generator component'''
|| Let me enter the data for the '''generator model'''.

* For this navigate to '''Generator''' tab.
* Open '''Generator parameter''' window. Let me enter the data for generator model.
* For this, navigate to generator tab, Open '''Generator parameter''' window
* We can see that there are '''Initialisation data, Power flow data '''and '''Machine parameters.'''
* Refer to the '''additional material''' section for the values to be entered.
* I am entering the values here and initialising '''e1q.start''' and '''e2q.start''' as''' true values'''.
* For this click on the checkbox which is to the left of the parameter. Then select “'''true:start-value is used to initialize'''”
* Now enter the rest of the '''parameters''' as shown.

|-
||
|| I have entered all the data here.
|-
|| Cursor pointing on the system data block
|| The '''system data block''' is used to set the '''System base''' and '''frequency'''.

In this case we can see it is set to '''100 MVA''' as system '''base''' and '''frequency''' as '''50 Hz'''.
|-
|| Double click on the components to open parameter window.
|| Now as the '''parameters and''' '''power flow data''' are set for all the components we are ready to simulate it.
|-
||

|| Before simulating the '''model''' save it to a desired location.
|-
|| Click on '''Check model'''
|| Firstly let us check the '''generator model''' by clicking on the tick mark icon at the top of the '''model'''.

Here we can see there are 66 equations in the '''model''' and 66 variables for '''generator model.'''

And doing the same for '''Network model''' gives 142 equations and 142 variables.

From this we can say the '''models''' are solvable.
|-
|| Close the Check Model windows
|| Close the '''messages browser'''.
|-
|| Click on the simulation setup
|| Let us proceed to the '''simulation''' of the '''network model.'''

Click on the '''Simulation Setup '''icon at the top of the '''model'''.

This is to set up the '''solver''' and other '''parameters''' for the '''simulation'''.
|-
|| Cursor on the simulation setup window.
|| Here, I am using '''dassl method''' and '''tolerance''' of '''1e-06'''.

The '''simulation '''time is set to 0 to 10 secs.

Make sure the "'''simulate'''" checkbox is checked before you click on "'''Ok'''".

Click on "'''Ok'''" which is at the bottom of the window and the '''simulation''' starts.
|-
|| Cursor on the Simulation output window
|| The '''simulation''' output window pops up.

This shows the compilation and running status of the '''simulation'''.

After the '''simulation''' is successful, close the '''simulation''' output window.
|-
|| Show Plotting perspective
|| We can see that the window has been changed to '''plotting '''perspective'''.'''

On the right hand side, we can see all the components are listed in the '''Variables browser''' tab.
|-
|| Expand the model and each component in variables browser.
|| Click on the '''Expand''' button which is on the left side of each component.

Now we can see all the variables under that particular component.
|-
||
|| Now let me show you the '''voltage profile''' at the''' fault bus''' i.e. '''Bus 2'''
|-
|| Show the '''variables browser'''
|| Click on the '''Expand''' button on the left hand side of '''Bus 2.'''

We can see all the '''parameters''' of the '''bus'''.

Now click on the checkbox which is on the left hand side of the '''voltage parameter (V).'''
|-
||
|| This plots the graph of '''Voltage''' at '''Bus 2'''. Let me close the '''Messages''' browser for better view.
|-
||
|| The Y-axis unit is in '''Per unit''' and the X-axis unit is in '''seconds'''.

Here we can see the plot starts from 0 seconds and ends at 10 secs.
|-
||
|| During the '''fault''' i.e. from the duration 0.5 to 0.57 secs, there is a huge dip in the '''voltage '''profile.
|-
||
|| After the '''fault''' is cleared at 0.57 secs the '''voltage''' rises quickly.
|-
|| Cursor on the voltage profile of Bus 2 plot.
|| As the system is a controlled one, the voltage has less oscillations about its '''steady state value'''.

pa

The '''voltage''' settles down after about 3.9 secs.

In this '''system''' the '''steady state stability''' is achieved in less time after the fault is cleared.

This is due to the additional '''controls''' such as '''AVR''' and '''PSS''' used in the '''system'''.
|-
||
|| Earlier in the series, the '''SMIB''' which was modelled, was an uncontrolled one.
|-
| |
| | Let’s compare the time taken by the uncontrolled '''system''' to that of a controlled one.

We can see the settling time is reduced.
|-
||
|| This indicates that '''system''' regained its stability in less time with the help of controls like '''AVR''' and '''PSS'''.
|-
|| Cursor on the voltage profile plot
|| Here we can also see that the '''voltage''' doesn't drop down to zero at this '''Bus''' though it is the '''fault bus'''.

This is because of the '''fault impedance''' involved.
|-
||
|| We can also view the '''voltage profiles''' of the other '''bus '''i.e''' B1'''.
|-
||
|| After selecting '''B2''' and '''B1 voltages''', we can clearly see the '''voltage drop''' between the '''buses'''.

This is the '''drop''' caused by the '''impedance''' of the '''transmission lines'''.
|-
|| Clear the plot
|| Now clear these plots by unchecking the '''parameter''' checkboxes.
|-
|| Show the plot of Delta curve of generator
|| We can also plot the '''Delta curve''' of the '''generator'''.

This indicates whether the system is accelerating or stable.
|-
|| Expand the '''generator''' and '''order61'''
|| For this, expand the '''generator''' and '''order61''' which is a '''sixth order generator. '''

Here we can see all the variables of '''generator'''.
|-
|| Click on the checkbox of '''delta'''
|| Click on the checkbox of '''delta''' to plot its graph.
|-
|| On the graph window
|| From the graph we can see the '''system''' is accelerated when the '''fault''' occurs at 0.5secs
|-
|| On the graph window
|| The '''Delta''' then oscillates about the''' steady-state value''' after the '''fault''' is cleared.

It settles downs at 5.26 secs making the '''system stable'''.
|-
|| '''Slide Number 14'''

Summary
|| This brings us to the end of this tutorial.

Let us now summarize.

In this tutorial, we have learnt:* How to simulate a controlled SMIB system

'''Modelling of a SMIB system using OpenIPSL'''
|| Earlier in this series, we have already seen how to* Simulate a '''SMIB system''' and
* Interpret its results
|-
|| '''Slide Number 6'''

'''What is a controlled SMIB system?'''
|| * In this tutorial, we’ll learn how to '''model''' a '''SMIB'''.
* Here the '''SMIB system''' which we are going to '''model''' is a '''controlled''' one.
* The '''generator''' is '''controlled''' with the help of '''Automatic Voltage Regulator(AVR)''' and '''Power System Stabilizer(PSS).'''
|-
||
|| * Before getting started we will briefly learn about '''Automatic Voltage Regulator (AVR) '''and '''Power System Stabilizer (PSS.)'''
|-
|| '''Slide Number 7'''

'''What is a controlled SMIB system?'''

|| '''Automatic Voltage Regulator(AVR)'''

* '''AVR''' regulates the '''generator terminal voltage'''
* This is done by controlling the amount of current supplied to the '''generator field winding''' by the '''exciter'''.
* '''AVR''' improves the '''voltage regulation''' of the '''system.'''
|-
|| '''Slide Number 8'''

'''What is a controlled SMIB system?'''
|| '''Power System Stabilizer(PSS)'''

* '''(PSS)''' is installed with '''AVR''' to '''damp''' the low frequency '''oscillations''' in the '''power system'''
* This is done by providing a '''supplementary signal''' to the '''excitation system'''.
* '''PSS''' improves the '''damping''' of the '''system.''

|-
|| '''Slide Number 9'''

'''What is a controlled SMIB system?'''
|| Optimal tuning of '''AVR controller''' and '''PSS parameters''' is necessary.

This helps to obtain better '''voltage regulation''' and '''oscillation damping''' in the '''system'''.
|-
|| '''Slide Number 10'''

'''How to model a SMIB system?'''
|| Before launching '''OMEdit '''let us look at the '''Single Line Diagram(SLD)''' of the '''SMIB system'''.

|-
|| '''Slide Number 11'''

'''How to model a SMIB system?'''
|| This '''SLD''' helps us to get an overview of our '''system.'''
|-
|| '''Launch OMEdit '''
|| Now let us launch '''OMEdit'''.
|-
|| '''Open OpenModelica and OpenIPSL'''
|| Once '''OMEdit''' is launched we will create a new '''Modelica Package'''.

Before creating it, let me include the '''OpenIPSL library'''.

As demonstrated earlier in the series, navigate to '''“File” --> “system libraries” --> “OpenIPSL”. '''
|-
|| '''Highlight and click on the icon which is below the file to the top left corner .'''
|| To create a new "'''Modelica Package'''", click on the icon at the top left corner below the file.

We see a pop-up window.
|-
|| '''Point at the name column.'''
|| Now type the desired name in the '''Name''' column.

While entering the name make sure there are no spaces and the name doesn't start with a number.

It also doesn't accept any special characters.
|-
|| '''Create a package with the name “SMIB_Controlled”'''

'''Highlight the package in libraries column.'''
|| Now I will type the name as "'''SMIB_Controlled'''".

In '''Specialization''' column dropdown, select '''Package''' and click on '''Ok'''.

We can see a '''package''' in the '''libraries''' column.

Under this '''package''' we will create the '''models'''.
|-
||
|| We have to create two '''models''' under this '''package'''

'''1. Network.'''

'''2. Generator.'''
|-
|| '''Create two models under the main package.'''

Click on "'''New Modelica class'''" >> type name="'''Network'''" and Specialization="'''Model'''".

|| Now to create the '''models''', right-click on the '''SMIB_Controlled package.'''

And click on "'''New Modelica class'''".

Type the name as "'''Network'''" and '''Specialization''' as "'''Model'''".
|-
|| Highlight the '''class '''column''' SMIB_Controlled '''

Click on "'''OK'''".
|| Here we can see that the '''Insert''' in '''class''' column is automatically filled as "'''SMIB_Controlled'''".

This is because we are inserting this '''model''' in the '''SMIB_Controlled package'''.

Click on "'''OK'''".
|-
|| Repeat the above procedure.
|| Now follow the same procedure to create '''Generator model'''.

While doing so, type the name of the '''model''' as “'''Generator'''”.
|-
|| Point to the '''Expand button''' >> click on it
|| After creating the '''models''' you can see the '''Expand''' button to the left of the '''package'''.

Expand the '''package''' by clicking on the '''Expand''' button.
|-
|| Open network model.
|| We can see two '''models''' already opened. Click on the '''network''' tab at the top.

Now let us drag and drop the required components to build the '''network'''.
|-
|| Open the slides

'''Slide number 12'''

|-
||
|| We require three '''Buses''' as mentioned earlier in the requirements.
|-
|| Repeat for '''Bus 2 '''and '''Bus 3'''
|| Now do the same for '''Bus 2''' and '''Bus 3'''.
|-
|| Drag and drop all the described components
|| In a similar manner, drag and drop all the required components.
|-
|| Drag and drop the required components on to network model window.

For '''Infinite Bus''' navigate to "'''OpenIPSL--> Electrical--> Buses--> InfiniteBus'''".

For '''Fault Block''' navigate to "'''OpenIPSL--> Electrical--> Events--> PwFault'''".

For '''System Data''' navigate to "'''OpenIPSL--> Electrical-->SystemBase'''".
|-
|| '''Go back to Slide Number 11 '''
|| From the single line diagram shown here, we can get a clear idea about the '''network'''.
|-
|| Go back to '''OMEdit'''.
|| Let us go back to '''OMEdit'''.

Let us connect the components together according to the single line diagram shown earlier.
|-
|| Connect the components as described
|| To connect two components, click on the '''pwpin''' of the first component.

Drag and click on the second '''pwpin''' as shown.
|-
|| Connect the components in Network model as shown in SLD.

'''Bus 2''' and '''Bus 3''' are connected via two power lines in parallel.
|-
|| Connect the components in Network model as shown in SLD.
|| The '''infinite bus''' is connected to '''Bus3.'''

But before that rotate the '''Infinite bus''' component using command "'''Ctrl+R'''"
|-
||
|| The '''Power Fault block''' is connected to '''Bus 2'''.
|-
|| Connect the components in Network model as shown in SLD.
|| The system data block is placed on the '''Network model plane'''.

This provides the system with '''base''' and '''frequency''' for all the other components.
|-
|| Switch to''' Generator model window'''
|| The '''Network''' is connected now and let us go to the '''Generator modelling''' window.

The '''Generator''' used here is of order six.
|-
|| Point to '''PSS '''and '''AVR'''
|| '''PSS''' and '''AVR''' are connected to the generator to achieve required control.
|-
|| Point to '''AVR'''
|| '''AVR''' controls the '''field voltage''' of the '''generator''' taking the '''generator terminal voltage''' as input.
|-
|| Point to '''PSS '''
|| The '''PSS''' takes ''''w'(Rotor speed)''' as the input and feeds '''AVR'''.
|-
|| Drag and drop components on to '''Generator modelling window'''
|| Now let us drag and drop '''PSS, AVR''' and '''Generator''' on to the '''Generator modelling''' window.
|-
|| Connect the components as described

|| For '''Generator (Order VI)''' navigate to "'''OpenIPSL--> Electrical--> Machines--> PSAT-->Order6'''".
|-
|| Connect the components as described
|| For Power Pin navigate to "'''OpenIPSL--> Interfaces--> PwPin'''".

This Power Pin acts as an interface between the '''Generator''' and '''Network models'''.
|-
|| Adjust and resize the components
|| Adjust and resize the components as shown to make it look better.
|-
|| Connect the components as described
|| Let us connect the components.

The '''AVR''' takes the '''generator terminal voltage''' as input i.e. '''Generator "V" '''is connected to '''AVRTypeIII "v"'''

The '''Initial Field voltage (Vf0)''' of the '''generator''' is given to '''AVRTypeIII''' as input.
|-
||
|| The output '''"Vf"''' of '''AVRTypeIII is''' connected to input '''"Vf"''' of the '''generator'''.
|-
|| Point to '''PSS input signal'''
|| The '''PSS input signal '''is connected to ''''w'(Rotor speed)''' of the '''generator'''.
|-
|| Point to the output of '''PSS '''
|| The output of '''PSS''' is fed to '''"Vs" '''of the '''AVRTypeIII'''.
|-
|| Point to the connection
|| The '''Mechanical''' power is not controlled here so '''Pm''' and '''Pm0''' of the '''generator''' are connected together.
|-
|| Point to '''PwPin'''
|| The Power '''pin''' of the '''generator''' is connected to '''PwPin'''.
|-
|| Point to '''PwPin'''
|| This '''PwPin''' acts as an interface between the two, '''Generator''' and '''Network classes.'''
|-
|| Shift to '''Icon view''' of the''' Generator model'''
|| Now shift to the icon view using the "'''Icon View'''".

This is at the top left corner of the '''Generator Modelling''' window.
|-
||
|| Here I will use a circle to represent my '''generator''' and its '''controls'''.
|-
|| Select the ellipse
|| Select the ellipse at the top toolbar to draw a circle as shown.
|-
|| Drag the cursor to draw a circle
|| After selecting eclipse, click on the top left corner and drag the cursor to draw a circle.
|-
|| '''Shift to network window and drag and drop Generator model onto it'''
|| Now let us go back to our '''network modelling''' window.

Here drag and drop the '''Generator model''' in your '''package'''.

|-
||
|| Navigate to "'''SMIB_Controlled-->Generator'''" and connect it to '''Bus1'''.

This makes the connections complete.
|-
||
|| We can use command "'''Ctrl+S'''" and then a pop-up opens up.

Here we can see there are 66 equations in the '''model''' and 66 variables for '''generator model.'''

And doing the same for '''Network model''' gives 142 equations and 142 variables.

From this we can say the '''models''' are solvable.

|| Show Plotting perspective
|| We can see that the window has been changed to '''plotting '''perspective'''.'''

On the right hand side, we can see all the components are listed in the '''Variables browser''' tab.

||
|| The Y-axis unit is in '''Per unit''' and the X-axis unit is in '''seconds'''.

Here we can see the plot starts from 0 seconds and ends at 10 secs.
|- style="background-color:#ffffff;border:1pt solid #000000;padding-top:0in;padding-bottom:0in;padding-left:0.0528in;padding-right:0.0528in;"
||
|| During the '''fault''' i.e. from the duration 0.5 to 0.57 secs, there is a huge dip in the '''voltage '''profile.
|- style="background-color:#ffffff;border:1pt solid #000000;padding-top:0in;padding-bottom:0in;padding-left:0.0528in;padding-right:0.0528in;"
||
|| After the '''fault''' is cleared at 0.57 secs the '''voltage''' rises quickly.
|- style="background-color:#ffffff;border:1pt solid #000000;padding-top:0in;padding-bottom:0in;padding-left:0.0528in;padding-right:0.0528in;"
|| Cursor on the voltage profile of Bus 2 plot.
|| As the system is a controlled one, the voltage has less oscillations about its '''steady state value'''.

pa

The '''voltage''' settles down after about 3.9 secs.

In this '''system''' the '''steady state stability''' is achieved in less time after the fault is cleared.

This is due to the additional '''controls''' such as '''AVR''' and '''PSS''' used in the '''system'''.
|- style="background-color:#ffffff;border:1pt solid #000000;padding-top:0in;padding-bottom:0in;padding-left:0.0528in;padding-right:0.0528in;"
||
|| Earlier in the series, the '''SMIB''' which was modelled, was an uncontrolled one.
|-

| style="border:1pt solid #000000;padding-top:0in;padding-bottom:0in;padding-left:0.0528in;padding-right:0.0528in;" | Let’s compare the time taken by the uncontrolled '''system''' to that of a controlled one.

We can see the settling time is reduced.
|- style="background-color:#ffffff;border:1pt solid #000000;padding-top:0in;padding-bottom:0in;padding-left:0.0528in;padding-right:0.0528in;"
||
|| This indicates that '''system''' regained its stability in less time with the help of controls like '''AVR''' and '''PSS'''.
|- style="background-color:#ffffff;border:1pt solid #000000;padding-top:0in;padding-bottom:0in;padding-left:0.0528in;padding-right:0.0528in;"
|| Cursor on the voltage profile plot
|| Here we can also see that the '''voltage''' doesn't drop down to zero at this '''Bus''' though it is the '''fault bus'''.

This is because of the '''fault impedance''' involved.
|- style="background-color:#ffffff;border:1pt solid #000000;padding-top:0in;padding-bottom:0in;padding-left:0.0528in;padding-right:0.0528in;"

|- style="background-color:#ffffff;border:1pt solid #000000;padding-top:0in;padding-bottom:0in;padding-left:0.0528in;padding-right:0.0528in;"
||
|| After selecting '''B2''' and '''B1 voltages''', we can clearly see the '''voltage drop''' between the '''buses'''.

This is the '''drop''' caused by the '''impedance''' of the '''transmission lines'''.
|- style="background-color:#ffffff;border:1pt solid #000000;padding-top:0in;padding-bottom:0in;padding-left:0.0528in;padding-right:0.0528in;"

'''eSim''' (previously known as Oscad / FreeEDA) is an open source EDA tool for circuit design, simulation, analysis and PCB design. It is an integrated tool built using open source software such as KiCad ([http://www.kicad-pcb.org/ http://www.kicad-pcb.org]) and Ngspice ([http://ngspice.sourceforge.net/ http://ngspice.sourceforge.net/]). eSim is released under GPL.

eSim offers similar capabilities and ease of use as any equivalent proprietary software for schematic creation, simulation and PCB design, without having to pay a huge amount of money to procure licenses. Hence it can be an affordable alternative to educational institutions and SMEs. It can serve as an alternative to commercially available/ licensed software tools like OrCAD, Xpedition and HSPICE.

Here the second '''argument '''is 1, so '''plot''' will not split '''vertically.'''

The last '''argument''' specifies the '''serial number '''for''' subplot'''.

Here we passed 1 as the '''argument''', which creates the '''upper subplot'''

* run basic '''Python '''commands on the '''ipython console'''
* use '''Plots''' interactively
* Embellish a '''plot'''

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Let us first open the '''Terminal '''by pressing '''Ctrl+Alt+T '''keys simultaneously.

Now, type '''ipython3''' and press '''Enter'''.

|-

'''x = linspace(0, 50, 500)'''

'''plot(x, cos(x))'''

'''y = linspace(0, 5, 100)'''

'''plot(y, y ** 2)'''

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"|

To compare two '''plots''' we draw the '''plots''' in the same '''plotting area.'''

Let us now create two plots, a cosine plot and an exponential curve in the same plotting area.

Type

'''x equals to linspace inside brackets 0 comma 50 comma 500 '''and press enter

'''plot inside brackets x comma cos(x).'''

'''y equals to linspace inside brackets 0 comma 5 comma 100.'''

''' '''

'''plot inside brackets y comma y square.'''

Here the two '''plots''' have different regular '''axes''' so we cannot draw '''overlaid plots. '''

|-

In such cases we can draw '''subplots'''.

We use '''subplot command''' to accomplish this

Type

'''clf()'''

'''subplot inside the brackets 2 comma 1 comma 1'''

The first '''argument''' is the number of '''rows''' of '''subplots''' that must be created.

Here the first '''argument''' is 2, to split''' '''the''' plot horizontally'''.

The second '''argument''' is the number of '''columns''' of '''subplots''' that must be created.

Here the second '''argument '''is 1, so '''plot''' will not split '''vertically.'''

The last '''argument''' specifies the '''serial number '''for''' subplot'''.

Here we passed 1 as the '''argument''', which creates the '''upper subplot'''

|-

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| If we execute the '''subplot command''' as

'''subplot inside the brackets 2 comma 1 comma 2'''

The '''lower subplot''' is created.

|-

'''x = linspace(0, 50, 500)'''

'''subplot(2, 1, 1)'''

'''plot(x, cos(x))'''

'''y = linspace(0, 5, 100)'''

'''subplot(2, 1, 2)'''

'''plot(y, y ** 2)'''

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Now we can draw plots in each of the '''subplot area''' using the '''plot command'''.

Type

'''subplot inside brackets 2 comma 1 comma 1'''

'''plot inside brackets x, cos(x)'''

'''subplot inside brackets 2 comma 1 comma 2 '''

'''plot inside brackets y comma y square'''

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| This created two '''plots''' one in each of the''' subplot''' area.

The top '''subplot''' holds a '''cosine curve''' and the bottom '''subplot''' holds a '''parabola'''.

It is clear from the two '''subplots''' that both have different '''regular axes'''.

For the '''cosine curve x-axis''' varies from 0 to 50 and '''y-axis''' varies from '''minus '''1 to 1.

For the '''parabolic curve x-axis''' varies from 0 to 5 and '''y-axis''' varies from 0 to 25.

'''Plot''' '''function''' does not '''plot''' the '''analytical function.'''

It plots the '''points''' given by the '''analytical function'''.

|-

Type '''legend inside the brackets square brackets commas sin(x) comma sin(y).'''

The '''legend''' '''command''' takes '''parameter '''as a '''list''' of '''strings.'''

Then it assigns '''strings''' to''' plots''' in the order they were created.

|-

Exercise 1

Draw two plots for the given form

# First plot is a parabola of the form '''y = 4(x ^ 2)'''
# Second plot is a '''straight line''' of the form '''y = 2x + 3''' in the '''interval''' -5 to 5.
# Use legends to indicate each plot.

Draw two '''plots''' first plot being a '''parabola''' of the form '''y equals to 4x square''' and the second being a '''straight line''' of the form '''y equals to 2x plus 3''' in the '''interval''' '''minus '''5 to 5.

Use '''legends''' to indicate what each '''plot''' is doing.

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [IPython Terminal]

'''x = linspace(-5, 5, 100)'''

'''plot(x, 4 * (x * x))'''

'''plot(x, (2 * x) + 3)'''
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| <Switch to the terminal for solution.>

Type '''x equals to linspace inside the brackets minus 5 comma 5 comma 100)'''

We can obtain the two '''plots''' in different '''colours''' using the following '''commands'''.

Type

'''plot inside the brackets x comma 4 multiplied by inisde the brackets x multiplied by x. '''

'''plot inside the brackets x comma (2 multiplied by x) plus 3)'''

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [IPython Terminal]

'''legend([r'$y = 4(x ^ 2)$', r'$y = 2x + 3$']) '''
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Now, we will add a legend to identify the plots

Type '''legend inside the brackets inside square brackets r inisde inverted commas dollar y equals to 4 x square dollar comma r inisde inverted commas dollar y equals to 2x plus 3 dollar. '''

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [Plot Window]
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| We can see the '''legend''' added to the plot.

<Pause>

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Next we will learn to '''switch''' between the '''plots''' and perform '''operations''' such as '''saving''' the '''plots''' etc.

Let us see how to accomplish this.

But before we move on, let us '''clear''' our '''screen'''.

Type '''clf()'''

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [IPython Terminal]

'''x = linspace(0, 50, 500) '''

'''figure(1)'''

'''plot(x, sin(x), 'b')'''

'''figure(2)'''

'''plot(x, cos(x), 'g')'''

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Switch to '''terminal'''

Type '''x equals to linspace inside the brackets 0 comma 50 comma 500 '''

To accomplish more control over '''individual plots''' we use the '''figure command '''

Type '''figure(1)'''

'''plot inside the brackets x comma sin(x) comma inisde inverted commas b'''

'''figure(2)'''

'''plot inside the brackets x comma cos(x) comma inisde inverted commas g'''

|-

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Now we have two''' plots''', a '''sine curve '''and a '''cosine curve''' in two different '''figures'''.

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [Ipython Terminal]

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| The '''figure command''' takes an '''integer''' as an '''argument. '''

This is''' '''the '''serial number''' of the '''plot''' to select corresponding '''plot'''.

All the''' plot commands '''we run hereafter are applied to the selected '''plot'''.

In this '''example, figure''' 1 is the '''sine plot''' and '''figure''' 2 is the '''cosine''' '''plot'''.

|-

'''title('cos(x)')'''

'''savefig('cosine.png')'''

'''figure(1)'''

'''title('sin(x)')'''

'''savefig('sine.png')'''
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| For example, we can '''save''' each''' plot '''separately.

Type

'''title inside brackets inisde inverted commas cos(x)'''

'''savefig inside brackets inisde inverted commas cosine.png'''

'''figure(1)'''

'''title inside brackets inisde inverted commas sin(x)'''

'''savefig inside brackets inisde inverted commas sine.png'''

The figures will be saved in current working directory. Now close both the plot windows.

Draw a '''line''' of the form '''y equals to x''' as one '''figure''' and another '''line''' of the form '''y equals to 2x plus 3'''.

Save each of them.

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Switch to the '''terminal''' for solution.

To solve this problem we will use the '''figure command''' to create first '''plotting area'''

Type

'''figure(1) '''

'''x equals to linspace inside the brackets minus 5 comma 5 comma 100'''

'''plot inside the brackets x comma x'''

|-

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Now use the '''figure command''' to create second '''plotting area''' and '''plot '''the''' figure'''

Type

'''figure(2) '''

'''plot inside the brackets x comma 2x plus 3'''

|-

'''plot(x, cos(x), 'r--',linewidth=3)'''

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Now type '''plot inisde brackets x comma cos(x) comma inside inverted commas r hypen hypen comma linewidth equals to 3'''

We use a combination of '''linewidth''' '''argument''' and '''linestyle'''.

Let us look at modifying the '''plot '''further.

|-

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Let us start with a '''plot''' for the '''function minus x square plus 4x minus 5. '''

Now type '''plot inside the brackets x comma minus x multiplied by x plus 4 multiplied by x minus 5 comma inisde inverted commas r comma linewidth equals to 2'''

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [Plot window]
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| We will see the curve of this equation in the '''plot '''window.

But the figure does not have any description describing the '''plot'''.

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [IPython console]

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| To add a title to the '''plot''', use the '''title''' '''command'''.

So type '''title inside the brackets inside inverted commas Parabolic function minus x square plus 4x minus 5'''

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [IPython console]

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Show the '''plot window''' and point to the title
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| We can see the''' title''' on the '''plot''' window.

But it is not '''formatted''' and does not look clean.

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Show the '''plot window''' and point to the title
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| It would look even more shabby if there were '''fractions''' and '''complex''' '''functions'''.

Let us write the''' title '''in''' LaTeX''' format for a neater look.

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [IPython console]

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| For '''LaTeX''' format, we put a '''$ '''before and after the '''string'''.

Type '''title inside the brackets r inside inverted commas Parabolic function dollar minus x square plus 4x minus 5 dollar'''

Here '''' r '''' means that the '''string''' is to be treated as a '''raw string'''.

It will ignore all '''escape codes'''.

|-

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| As we can see that the '''polynomial''' in the '''title '''is now '''formatted'''.

|-

So we will '''label''' '''x''' and '''y''' '''axes''' in Latex style.

Type '''xlabel inside the brackets r insde inverted commas dollar x dollar '''and''' ylabel inside brackets r insde inverted commas dollar y dollar '''

|-

Now we will name the '''points''' considering '''point(2 comma minus 1)''' as '''local maxima'''.

To name a '''point''' we use the '''function''' '''annotate'''.

Type '''annotate inside the brackets insde inverted commas local maxima comma xy equals to inside brackets 2 comma minus 1'''

The second '''argument''' represents the '''coordinates '''of''' '''the '''point'''.

It is a '''tuple''' containing two numbers. The first is '''x coordinate''' and second is '''y coordinate'''.

'''xlim function '''returns the current '''x axis limits.'''

Then type '''ylim brackets'''

'''ylim function''' returns the current '''y-axis limits'''.

Type '''x = linspace inside the brackets minus 2 comma 4 comma 20 '''and press '''Enter.'''

|-

The default colour and thickness of the line is as decided by '''pylab'''.

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"|

We can pass additional '''arguments '''to the '''plot command '''to do this.

|-

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Now '''plot''' the same '''sine curve '''with an additional '''color''' '''argument'''.

So we will type '''plot inside the brackets x comma sin(x) comma inside inverted commas r '''and press '''Enter.'''

Here, the '''argument 'r' '''is for red color.

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Show the sine curve on the plot window by moving the mouse pointer on it.

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| We can alter the thickness of the line by using the ''''linewidth' argument'''.

|-

So, type '''plot inside the brackets x comma cos(x) comma linewidth equals to 2 '''and press '''Enter.'''

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [Plot window]

|-

'''clf()'''
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| First let us clear the '''plot '''window by typing '''clf(). '''

You will again see a blank plot window.

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [IPython console]

'''plot(x, sin(x), 'b', linewidth=3)'''
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Now type''' plot inside the brackets x comma sin(x) comma inside inverted commas b comma linewidth equals to 3'''

A combination of '''color''' and '''linewidth''' would do the job for us.

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [Ipython console]
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| To get the '''plot '''in dotted style instead of a solid style, put a '''dot''' in '''linestyle.'''

|-

'''clf() '''
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| First, type '''clf() '''to clear the '''plot '''window.

'''plot(x, sin(x), '.')'''

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Now type '''plot inside the brackets x comma sin(x) comma inside inverted commas dot.'''

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| We get the '''sine curve '''in dotted style.

|-

'''Plot''' the '''curve''' of '''x v/s cos(x)''' in red '''dash line''' and '''linewidth''' 3.

|-

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Let us switch to the '''console '''for the solution.

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [IPython console]

'''clf()'''
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Type '''clf() '''to clear the '''plot '''window.

|-

'''plot(x, cos(x), 'r--',linewidth=3)'''

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Now type '''plot inisde brackets x comma cos(x) comma inside inverted commas r hypen hypen comma linewidth equals to 3'''

We use a combination of '''linewidth''' '''argument''' and '''linestyle'''.

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"|
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Now we know how to produce a '''bare minimum plot''' with '''color''', '''style''' and '''thickness'''.

Let us look at modifying the '''plot '''further.

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [IPython console]

'''plot(x, -x*x + 4*x - 5, 'r', linewidth=2) '''
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Let us start with a '''plot''' for the '''function -x^2 + 4x - 5. '''

Now type '''plot inside the brackets x comma minus x multiplied by x plus 4 multiplied by x minus 5 comma inisde inverted commas r comma linewidth equals to 2'''

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [Plot window]
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| We will see the curve of this equation in the '''plot '''window.

But the figure does not have any description describing the '''plot'''.

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [IPython console]

'''title("Parabolic function -x^2+4x-5")'''
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| To add a title to the '''plot''', use the '''title''' '''command'''.

So type '''title inside the brackets inside inverted commas Parabolic function minus x square plus 4x minus 5'''

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [IPython console]

Highlight the '''title '''command
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| The '''title''' command as you can see, takes a '''string''' as an '''argument.'''

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Show the '''plot window''' and point to the title
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| We can see the''' title''' on the '''plot''' window.

But it is not '''formatted''' and does not look clean.

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Show the '''plot window''' and point to the title
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| It would look even more shabby if there were '''fractions''' and '''complex''' '''functions'''.

Let us write the''' title '''in''' LaTeX''' format for a neater look.

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [IPython console]

'''title(r"Parabolic function $-x^2+4x-5$") '''
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| For '''LaTeX''' format, we put a '''$ '''before and after the '''string'''.

Type '''title inside the brackets r inside inverted commas Parabolic function dollar minus x square plus 4x minus 5 dollar'''

Here '''' r '''' means that the '''string''' is to be treated as a '''raw string'''.

It will ignore all '''escape codes'''.

|-

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| As we can see that the '''polynomial''' in the '''title '''is now '''formatted'''.

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [IPython console]

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Although we have '''title''', the '''plot''' is not complete without labelling the '''x '''and '''y axes'''.

So we will '''label''' '''x''' and '''y''' '''axes''' in Latex style.

Type '''xlabel inside the brackets r insde inverted commas dollar x dollar '''and''' ylabel inside brackets r insde inverted commas dollar y dollar '''

|-

Now we will name the '''points''' considering '''point(2,-1)''' as '''local maxima'''.

To name a '''point''' we use the '''function''' '''annotate'''.

Type '''annotate inside the brackets insde inverted commas local maxima comma xy equals to inside brackets 2 comma -1'''

* run basic '''Python '''commands on the '''ipython console'''
* use '''Plots''' interactively
* Embellish a '''plot'''

If not, see the pre-requisite '''Python '''tutorials on this website.

|-

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Let us first open the '''Terminal '''by pressing '''Ctrl+Alt+T '''keys simultaneously.

Now, type '''ipython3''' and press '''Enter'''.

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [IPython console]

'''%pylab '''and press '''Enter.'''
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Let us initialise the pylab package

Type '''%pylab '''and press''' Enter'''

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"|

[IPython Terminal]

'''x = linspace(0, 50, 500)'''

'''plot(x, cos(x))'''

'''y = linspace(0, 5, 100)'''

'''plot(y, y ** 2)'''

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"|

To compare two '''plots''' we draw the '''plots''' in the same '''plotting area.'''

Let us now create two plots, a cosine plot and an exponential curve in the same plotting area.

Type

'''x equals to linspace inside brackets 0 comma 50 comma 500 '''and press enter

'''plot inside brackets x comma cos(x).'''

'''y equals to linspace inside brackets 0 comma 5 comma 100.'''

''' '''

'''plot inside brackets y comma y square.'''

|-

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"|

Here the two '''plots''' have different regular '''axes''' so we cannot draw '''overlaid plots. '''

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"|

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"|

In such cases we can draw '''subplots'''.

We use '''subplot command''' to accomplish this

Type

'''clf()'''

'''subplot inside the brackets 2 comma 1 comma 1'''

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [Plot Window]
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| We can see the first '''subplot'''.

|-

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| The '''subplot''' '''command''' takes three '''arguments.'''

The first '''argument''' is the number of '''rows''' of '''subplots''' that must be created.

Here the first '''argument''' is 2, to split''' '''the''' plot horizontally'''.

The second '''argument''' is the number of '''columns''' of '''subplots''' that must be created.

Here the second '''argument '''is 1, so '''plot''' will not split '''vertically.'''

The last '''argument''' specifies the '''serial number '''for''' subplot'''.

Here we passed 1 as the '''argument''', which creates the '''upper subplot'''

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [IPython Terminal]

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| If we execute the '''subplot command''' as

'''subplot inside the brackets 2 comma 1 comma 2'''

The '''lower subplot''' is created.

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [Plot Window]
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Here, we can see two '''subplots'''.

|-

'''x = linspace(0, 50, 500)'''

'''subplot(2, 1, 1)'''

'''plot(x, cos(x))'''

'''y = linspace(0, 5, 100)'''

'''subplot(2, 1, 2)'''

'''plot(y, y ** 2)'''

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Now we can draw plots in each of the '''subplot area''' using the '''plot command'''.

Type

'''subplot inside brackets 2 comma 1 comma 1'''

'''plot inside brackets x, cos(x)'''

'''subplot inside brackets 2 comma 1 comma 2 '''

'''plot inside brackets y comma y square'''

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [Plot window]
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| This created two '''plots''' one in each of the''' subplot''' area.

The top '''subplot''' holds a '''cosine curve''' and the bottom '''subplot''' holds a '''parabola'''.

It is clear from the two '''subplots''' that both have different '''regular axes'''.

For the '''cosine curve x-axis''' varies from 0 to 50 and '''y-axis''' varies from -1 to 1.

For the '''parabolic curve x-axis''' varies from 0 to 5 and '''y-axis''' varies from 0 to 25.

|-

'''Pressure, Volume '''and''' Temperatures '''are held by the '''equation PV = nRT''' where '''nR''' is a '''constant'''.

A'''ssume''' '''nR =0.01 Joules/Kelvin''' and '''T = 200K'''. V can be in the '''range''' from '''21cc to 100cc'''.

Draw two different''' plots '''as''' subplots''':

'''v equals to linspace inside brackets 21 comma 100 comma 500'''

'''subplot(2, 1, 1) '''

'''plot(v, 2.0/v)'''

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| We can create first '''subplot''' and draw '''Pressure''' v/s '''Volume''' '''graph '''using this '''v'''.

'''subplot(2, 1, 1) '''

'''plot(v, 2.0 by v)'''

We know that '''nRT''' is a '''constant''' which is equal to 2.0 since '''nR''' = 0.01 '''Joules/Kelvin''' and '''T '''<nowiki>= 200 </nowiki>'''Kelvin '''

|-

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Now we can create the second '''subplot''' and draw the '''Pressure''' v/s '''Temperature plot''' as follows

'''subplot(2 comma 1 comma 2)'''

'''plot(200 comma 2.0 divided by v)'''

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [IPython Terminal]

'''t = linspace(200, 200, 500) '''

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| We have an '''error''' now, telling x and y '''dimensions''' don't match.

So we will create same number of '''points''' for '''temperature.'''

Type

'''t = linspace inside brackets 200 comma 200 comma 500. '''

|-

Exercise 1

Draw two plots for the given form

# First plot is a parabola of the form '''y = 4(x ^ 2)'''
# Second plot is a '''straight line''' of the form '''y = 2x + 3''' in the '''interval''' -5 to 5.
# Use legends to indicate each plot.

Draw two '''plots''' first plot being a '''parabola''' of the form '''y = 4(x ^ 2)''' and the second being a '''straight line''' of the form '''y = 2x + 3''' in the '''interval''' -5 to 5.

Use '''legends''' to indicate what each '''plot''' is doing.

|-

'''x = linspace(-5, 5, 100)'''

'''plot(x, 4 * (x * x))'''

'''plot(x, (2 * x) + 3)'''
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| <Switch to the terminal for solution.>

Type '''x = linspace inside the brackets minus 5 comma 5 comma 100)'''

We can obtain the two '''plots''' in different '''colours''' using the following '''commands'''.

Type

'''plot inside the brackets x comma 4 multiplied by inisde the brackets x multiplied by x. '''

'''plot inside the brackets x comma (2 multiplied by x) plus 3)'''

|-

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Now, we will add a legend to identify the plots

Type '''legend inside the brackets inside square brackets r inisde inverted commas dollar y equals to 4xsquare dollar comma r inisde inverted commas dollar y equals to 2x plus 3 dollar. '''

|-

Let us see how to accomplish this.

But before we move on, let us '''clear''' our '''screen'''.

Type '''clf()'''

|-

'''x = linspace(0, 50, 500) '''

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Switch to '''terminal'''

Type '''x equals to linspace inside the brackets 0 comma 50 comma 500 '''

To accomplish more control over '''individual plots''' we use the '''figure command '''

Type '''figure(1)'''

'''plot inside the brackets x comma sin(x) comma inisde inverted commas b'''

'''figure(2)'''

'''plot inside the brackets x comma cos(x) comma inisde inverted commas g'''

|-

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Now we have two''' plots''', a '''sine curve '''and a '''cosine curve''' in two different '''figures'''.

|-

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| The '''figure command''' takes an '''integer''' as an '''argument. '''

This is''' '''the '''serial number''' of the '''plot''' to select corresponding '''plot'''.

All the''' plot commands '''we run hereafter are applied to the selected '''plot'''.

In this '''example, figure''' 1 is the '''sine plot''' and '''figure''' 2 is the '''cosine''' '''plot'''.

|-

'''title('cos(x)')'''

'''savefig('cosine.png')'''

'''figure(1)'''

'''title('sin(x)')'''

'''savefig('sine.png')'''
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| For example, we can '''save''' each''' plot '''separately.

Type

'''title inside brackets inisde inverted commas cos(x)'''

'''savefig inside brackets inisde inverted commas cosine.png'''

'''figure(1)'''

'''title inside brackets inisde inverted commas sin(x)'''

'''savefig inside brackets inisde inverted commas sine.png'''

The figures will be saved in current working directory. Now close both the plot windows.

Draw a '''line''' of the form '''y = x''' as one '''figure''' and another '''line''' of the form '''y = 2x + 3'''.

Save each of them.

To solve this problem we will use the '''figure command''' to create first '''plotting area'''

Type

'''figure(1) '''

'''x equals to linspace inside the brackets minus 5 comma 5 comma 100'''

'''plot inside the brackets x comma x'''

|-

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Now use the '''figure command''' to create second '''plotting area''' and '''plot '''the''' figure'''

Type

'''figure(2) '''

'''plot inside the brackets x comma (2 * x) plus 3))'''

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [IPython Terminal]

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Now to switch between the '''figures''' we can use '''figure command'''.

We will save the figure as follows

Type

'''figure(1)'''

'''savefig inside brackets inisde inverted commas plot1.png '''

Now let us see how to '''save''' the '''plot.'''

|-

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| For saving the plot, we will use the '''savefig()''' function.

Syntax: '''savefig(fname)'''

'''savefig''' function takes one argument which is the filename.

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [IPython Terminal]

'''savefig('sine.png')'''

This saves the file in present working directory.

The characters after the '''dot '''in the filename is the extension.

It determines the format in which you want to save.

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [IPython Terminal]

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| To check current working directory,

Type '''pwd '''in the '''console''' and press '''Enter'''

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [IPython Terminal]

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Note that above''' file path '''is for''' Linux based file systems.'''

For''' windows based systems, '''type corresponding''' path.'''

Example:''' '''if the''' username '''in''' windows '''is''' fossee,'''

and '''sine.png '''is to be saved on '''Desktop'''

Then filepath is -

''''C:\\Users\\fossee\\Desktop\\sine.png' '''

Now type '''plot inside brackets x comma minus x multiplied by x plus 4 multiplied by x minus 5 comma inisde inverted commas r comma linewidth equals to 2'''

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [Plot window]
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| We will see the curve of this equation in the '''plot '''window.

But the figure does not have any description describing the '''plot'''.

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [IPython console]

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| To add a title to the '''plot''', use the '''title''' '''command'''.

So type '''title inside the brackets inside inverted commas Parabolic function minus x square plus 4x minus 5'''

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [IPython console]

But it is not '''formatted''' and does not look clean.

|-

Let us write the''' title '''in''' LaTeX''' format for a neater look.

|-

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| For '''LaTeX''' format, we put a '''$ '''before and after the '''string'''.

Type '''title inside the brackets r inside inverted commas Parabolic function dollar minus x square plus 4x minus 5'''

Here '''' r '''' means that the '''string''' is to be treated as a '''raw string'''.

It will ignore all '''escape codes'''.

|-

So we will '''label''' '''x''' and '''y''' '''axes''' in Latex style.

Type '''xlabel inside the brackets r insde inverted commas dollar x dollar '''and''' ylabel inside the brackets r insde inverted commas dollar y dollar '''

Now we will name the '''points''' considering '''point(2,-1)''' as '''local maxima'''.

To name a '''point''' we use the '''function''' '''annotate'''.

Type '''annotate inside the brackets insde inverted commas local maxima comma xy equals to inside brackets 2 comma -1'''

* run basic '''Python '''commands on the '''ipython console'''
* use '''Plots''' interactively
* Embellish a '''plot'''

If not, see the pre-requisite '''Python '''tutorials on this website.

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Let us first open the '''Terminal '''by pressing '''Ctrl+Alt+T '''keys simultaneously.

Now, type '''ipython3''' and press '''Enter'''.

|-

'''x = linspace(0, 50, 500)'''

'''plot(x, cos(x))'''

'''y = linspace(0, 5, 100)'''

'''plot(y, y ** 2)'''

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"|

To compare two '''plots''' we draw the '''plots''' in the same '''plotting area.'''

Let us now create two plots, a cosine plot and an exponential curve in the same plotting area.

Type

'''x = linspace(0, 50, 500)'''

'''plot(x, cos(x))'''

'''y '''<nowiki>=</nowiki>''' linspace(0, 5, 100)'''

''' '''

'''plot(y, y ** 2)'''

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"|

Here the two '''plots''' have different regular '''axes''' so we cannot draw '''overlaid plots. '''

|-

We use '''subplot command''' to accomplish this

Type

The first '''argument''' is the number of '''rows''' of '''subplots''' that must be created.

Here the first '''argument''' is 2, to split''' '''the''' plot horizontally'''.

The second '''argument''' is the number of '''columns''' of '''subplots''' that must be created.

Here the second '''argument '''is 1, so '''plot''' will not split '''vertically.'''

The last '''argument''' specifies the '''serial number '''for''' subplot'''.

Here we passed 1 as the '''argument''', which creates the '''upper subplot'''

|-

'''subplot(2, 1, 2)'''

The '''lower subplot''' is created.

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Now we can draw plots in each of the '''subplot area''' using the '''plot command'''.

'''plot(y, y ** 2)'''

The top '''subplot''' holds a '''cosine curve''' and the bottom '''subplot''' holds a '''parabola'''.

It is clear from the two '''subplots''' that both have different '''regular axes'''.

For the '''cosine curve x-axis''' varies from 0 to 50 and '''y-axis''' varies from -1 to 1.

For the '''parabolic curve x-axis''' varies from 0 to 5 and '''y-axis''' varies from 0 to 25.

Exercise 1

Draw two plots for the given form

# First plot is a parabola of the form '''y = 4(x ^ 2)'''
# Second plot is a '''straight line''' of the form '''y = 2x + 3''' in the '''interval''' -5 to 5.
# Use legends to indicate each plot.

Draw two '''plots''' first plot being a '''parabola''' of the form '''y = 4(x ^ 2)''' and the second being a '''straight line''' of the form '''y = 2x + 3''' in the '''interval''' -5 to 5.

Use '''legends''' to indicate what each '''plot''' is doing.

'''x = linspace(-5, 5, 100)'''

Type '''x = linspace inside the brackets (-5, 5, 100)'''

We can obtain the two '''plots''' in different '''colours''' using the following '''commands'''.

Type

'''plot inside the brackets (x, 4 * (x * x)) '''

'''plot inside the brackets (x, (2 * x) + 3)'''

Let us see how to accomplish this.

But before we move on, let us '''clear''' our '''screen'''.

Type '''clf()'''

|-

'''x = linspace(0, 50, 500) '''

'''figure(1)'''

'''plot(x, sin(x), 'b')'''

'''figure(2)'''

'''plot(x, cos(x), 'g')'''

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Switch to '''terminal'''

Type '''x = linspace inside the brackets (0, 50, 500) '''

To accomplish more control over '''individual plots''' we use the '''figure command '''

Type '''figure(1)'''

'''plot inside the brackets (x, sin(x), 'b')'''

'''figure(2)'''

'''plot inside the brackets (x, cos(x), 'g')'''

|-

Syntax: '''savefig(fname)'''

'''savefig''' function takes one argument which is the filename.

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| [IPython Terminal]

This saves the file in present working directory.

The characters after the '''dot '''in the filename is the extension.

It which determines the format in which you want to save.

|-

type full path of the directory before the filename.

<nowiki>## WILL CHANGE FILE PATHS </nowiki>WHILE RECORDING ##

Type '''savefig('/home/fossee/sine.png')'''

|-
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"|
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0in;padding-bottom:0in;padding-left:0.0382in;padding-right:0.075in;"| Note that above''' file path '''is for''' Linux based file systems.'''

For''' windows based systems, '''type corresponding''' path.'''

Example:''' '''if the''' username '''in''' windows '''is''' fossee,'''

and '''sine.png '''is to be saved on '''Desktop'''

Then filepath is -

''''C:\\Users\\fossee\\Desktop\\sine.png' '''

|-

Type ''''linspace'''' followed by a question mark in '''ipython console.'''

Please note that the '''command '''is''' linspace '''and''' '''not''' linespace.'''

Here, 1 is the '''start''' , 100 is the '''stop''' and the next 100 is the number of points.

Now, press '''Enter'''. As you can see, a sequence of numbers from 1 to 100 is displayed.

|-
| style="border-top:none;border-bottom:0.5pt solid #000000;border-left:0.5pt solid #000000;border-right:0.5pt solid #000000;padding-top:0in;padding-bottom:0.0417in;padding-left:0.0417in;padding-right:0.0417in;"| [iPython console]

We do that by typing '''linspace brackets (0, 1, 200)'''.

Here, 0 is the '''start''' , 1 is the '''stop''' and 200 is the number of points.

Now, press '''Enter'''.

Here is the expected sequence of numbers.

First we will generate 100 points between '''-pi''' and '''pi'''.

So type '''linspace brackets (-pi, pi, 100)'''

Here ''''pi'''' is a constant defined by '''pylab'''.

|-
| style="border-top:none;border-bottom:0.5pt solid #000000;border-left:0.5pt solid #000000;border-right:0.5pt solid #000000;padding-top:0in;padding-bottom:0.0417in;padding-left:0.0417in;padding-right:0.0417in;"| [iPython console]

|-
| style="border-top:none;border-bottom:0.5pt solid #000000;border-left:0.5pt solid #000000;border-right:0.5pt solid #000000;padding-top:0in;padding-bottom:0.0417in;padding-left:0.0417in;padding-right:0.0417in;"| [iPython console]

Type '''plot(t, cos(t)) '''and press '''Enter.'''

|-
| style="border-top:none;border-bottom:0.5pt solid #000000;border-left:0.5pt solid #000000;border-right:0.5pt solid #000000;padding-top:0in;padding-bottom:0.0417in;padding-left:0.0417in;padding-right:0.0417in;"|

This feature of '''IPython''' is called the '''tab-completion'''.

|-
| style="border-top:none;border-bottom:0.5pt solid #000000;border-left:0.5pt solid #000000;border-right:0.5pt solid #000000;padding-top:0in;padding-bottom:0.0417in;padding-left:0.0417in;padding-right:0.0417in;"| [IPython Terminal]

Just type '''p''' and then press the tab.

|-
| style="border-top:none;border-bottom:0.5pt solid #000000;border-left:0.5pt solid #000000;border-right:0.5pt solid #000000;padding-top:0in;padding-bottom:0.0417in;padding-left:0.0417in;padding-right:0.0417in;"| [IPython Terminal]

This is because, there are more than one '''command''' beginning with '''p'''.

Therefore, it just lists out all the possible '''tab-completion''' of '''p'''.

First open the '''terminal '''by pressing '''Ctrl+Alt+T '''keys simultaneously on the keyboard.

Type '''ipython3''' at the '''prompt''' and press '''Enter'''.

If '''IPython''' is not installed, please refer to the instructions sheet.

|-

Type '''y''' for '''yes''' and quit '''IPython'''.

Note that '''y''' is given in '''square brackets '''so it is default.

We could also press '''Enter''' and it will exit.

Else type '''n '''for '''no '''if you don't want to quit '''IPython'''.

We press '''Enter''' to execute the '''python''' '''command'''. Please do so after typing every '''command'''.

'''IPython''' promptly displays the output as 3.

Notice that the output is shown with an '''Out square brackets 1''' indication.

5 minus 3,

7 multiplied by 4,

Each time we press '''Enter''' and see the output on the '''IPython console window.'''

Instead of typing the whole '''command''', we can recall the '''command''' '''1 plus 2 '''we typed earlier.

|-
| style="border-top:none;border-bottom:0.5pt solid #000000;border-left:0.5pt solid #000000;border-right:0.5pt solid #000000;padding-top:0in;padding-bottom:0.0417in;padding-left:0.0417in;padding-right:0.0417in;"| [IPython Terminal]

Use the up arrow key to go back to the '''command''' 1+2.
| style="border-top:none;border-bottom:0.5pt solid #000000;border-left:0.5pt solid #000000;border-right:0.5pt solid #000000;padding-top:0in;padding-bottom:0.0417in;padding-left:0.0417in;padding-right:0.0417in;"| Use the up arrow key to go back to the '''command 1 plus 2'''.

Highlight the result line.

Point at the '''Output'''

We use the up arrow key to navigate to the previous '''command print (1 plus 2)'''.

|-
| style="border-top:none;border-bottom:0.5pt solid #000000;border-left:0.5pt solid #000000;border-right:0.5pt solid #000000;padding-top:0in;padding-bottom:0.0417in;padding-left:0.0417in;padding-right:0.0417in;"| [IPython Terminal]

Change '''print (1+2) '''to '''print (10*2)'''

Let us consider an example.

|-
| style="border-top:none;border-bottom:0.5pt solid #000000;border-left:0.5pt solid #000000;border-right:0.5pt solid #000000;padding-top:0in;padding-bottom:0.0417in;padding-left:0.0417in;padding-right:0.0417in;"| [IPython Terminal]

'''pri'''<tab>
| style="border-top:none;border-bottom:0.5pt solid #000000;border-left:0.5pt solid #000000;border-right:0.5pt solid #000000;padding-top:0in;padding-bottom:0.0417in;padding-left:0.0417in;padding-right:0.0417in;"| Suppose we want to use the '''function print'''.

For this we just type '''pri''' at the prompt and press the '''tab''' '''key'''.

|-
| style="border-top:none;border-bottom:0.5pt solid #000000;border-left:0.5pt solid #000000;border-right:0.5pt solid #000000;padding-top:0in;padding-bottom:0.0417in;padding-left:0.0417in;padding-right:0.0417in;"| [IPython Terminal]
| style="border-top:none;border-bottom:0.5pt solid #000000;border-left:0.5pt solid #000000;border-right:0.5pt solid #000000;padding-top:0in;padding-bottom:0.0417in;padding-left:0.0417in;padding-right:0.0417in;"| As you can see on the console that '''IPython''' has autocompleted the '''command''' '''pri''' to '''print'''.

This feature of '''IPython''' is called the '''tab-completion'''.

|-
| style="border-top:none;border-bottom:0.5pt solid #000000;border-left:0.5pt solid #000000;border-right:0.5pt solid #000000;padding-top:0in;padding-bottom:0.0417in;padding-left:0.0417in;padding-right:0.0417in;"| [IPython Terminal]

'''p'''<tab>
| style="border-top:none;border-bottom:0.5pt solid #000000;border-left:0.5pt solid #000000;border-right:0.5pt solid #000000;padding-top:0in;padding-bottom:0.0417in;padding-left:0.0417in;padding-right:0.0417in;"| Let us see some more possibilities of '''tab completion'''.

Just type '''p''' and then press the tab.

|-
| style="border-top:none;border-bottom:0.5pt solid #000000;border-left:0.5pt solid #000000;border-right:0.5pt solid #000000;padding-top:0in;padding-bottom:0.0417in;padding-left:0.0417in;padding-right:0.0417in;"| [IPython Terminal]
| style="border-top:none;border-bottom:0.5pt solid #000000;border-left:0.5pt solid #000000;border-right:0.5pt solid #000000;padding-top:0in;padding-bottom:0.0417in;padding-left:0.0417in;padding-right:0.0417in;"| In this case, we see that '''IPython''' does not complete the '''command'''.

This is because, there are more than one '''command''' beginning with '''p'''.

Therefore, it just lists out all the possible '''tab-completion''' of '''p'''.

From the displayed information, it says '''abs''' accepts a number as input and returns it's absolute value.

|-
| style="border-top:none;border-bottom:0.5pt solid #000000;border-left:0.5pt solid #000000;border-right:0.5pt solid #000000;padding-top:0in;padding-bottom:0.0417in;padding-left:0.0417in;padding-right:0.0417in;"| [Ipython Terminal]

'''abs(-19)'''

'''abs(19) '''

On the '''console''', type '''abs(-19)''' and then '''abs(19)'''.

We get 19, as expected, in both the cases.

|-

Try out the following exercise and resume the video.

Look-up the documentation of '''round''' and see how to use it.

You can look up the documentation of the '''function round''' by typing '''round''' '''question mark'''.

It says here that the '''function round''', '''rounds''' a number to a given '''precision'''.

|-
| style="border-top:none;border-bottom:0.5pt solid #000000;border-left:0.5pt solid #000000;border-right:0.5pt solid #000000;padding-top:0in;padding-bottom:0.0417in;padding-left:0.0417in;padding-right:0.0417in;"| [IPython Terminal]

Notice, there are extra square brackets around '''ndigits'''.

This means that '''ndigits''' is optional and 0 is the default value.

Optional parameters are shown in square brackets in '''Python''' documentation.

In such case, we can press '''Ctrl+C''' keys, to interrupt the '''command''' and get back to the '''IPython prompt'''.

E.g, '''round''' takes only numbers as input. Type '''round(1a'''

Do not close the paranthesis and press''' Enter. '''

We gave alpha-numeric value ''''1a'''' as input.

Press''' Ctrl+C''' to iterrupt the execution.

'''round'''(2.484

Press '''Enter'''

Let us make a typing error deliberately.

Type '''round(2.484''' and press '''Enter''', without closing the parenthesis.

Point at the prompt with three dots

| style="border-top:none;border-bottom:0.5pt solid #000000;border-left:0.5pt solid #000000;border-right:0.5pt solid #000000;padding-top:0in;padding-bottom:0.0417in;padding-left:0.0417in;padding-right:0.0417in;"| We get a '''prompt '''with dots.

This '''prompt '''is the continuation '''prompt '''of '''IPython'''.

It appears when, the previous line is incomplete.

In such case, we can press '''Ctrl+C''' keys, to interrupt the '''command''' and get back to the '''IPython prompt'''.

E.g, '''round''' takes only numbers as input. Type '''round(1a'''

Do not close the paranthesis and press''' Enter. '''

We gave alpha-numeric value ''''1a'''' as input.

Press''' Ctrl+C''' to iterrupt the execution.
