* '''if/else blocks'''
* '''if/elif/else blocks'''
* '''Ternary''' '''conditional''' '''statement '''and
* '''Pass statement'''

|-

* '''Ubuntu Linux 16.04''' operating system
* '''Python 3.4.3'''
* '''IPython 5.1.0'''

|-
| style="background-color:#ffffff;border-top:0.5pt solid #000001;border-bottom:0.5pt solid #000001;border-left:0.5pt solid #000001;border-right:none;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;"| Show Slide

Pre-requisite

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;"| To practice this tutorial, you should know how to use

* basic''' data types '''and '''operators '''
* '''strings '''and '''Input/Output statements'''

If not, see the relevant Python tutorials on this website.

|-
| style="background-color:#ffffff;border-top:0.5pt solid #000001;border-bottom:0.5pt solid #000001;border-left:0.5pt solid #000001;border-right:none;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;"| Show Slide

'''if condition'''

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;"| First let us learn about''' if condition. '''

'''if condition '''is used to decide whether to execute the statements in the '''if block '''or not.

Here is the syntax.

|-
| style="background-color:#ffffff;border-top:0.5pt solid #000001;border-bottom:0.5pt solid #000001;border-left:0.5pt solid #000001;border-right:none;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;"| Show Slide

'''if else condition'''

Box line by line

Highlight ''':'''

Highlight 4 spaces
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;"| Next we will see about '''if else condition'''.

When the test condition is true, it will execute the body of '''if'''.

If the condition is '''False''', body of the '''else''' is executed.

Note that, '''if''' and '''else''' statements end with a colon.

This denotes the beginning of the code block of '''True''' or '''False''' condition.

All the '''statements''' inside a '''code block''' are '''indented''' by 4 spaces.

|-
| style="background-color:#ffffff;border-top:0.5pt solid #000001;border-bottom:0.5pt solid #000001;border-left:0.5pt solid #000001;border-right:none;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;"| Open the '''terminal'''
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;"| Let us start '''ipython.'''

Open the '''terminal'''.

|-
| style="background-color:#ffffff;border-top:0.5pt solid #000001;border-bottom:0.5pt solid #000001;border-left:0.5pt solid #000001;border-right:none;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;"| Type '''ipython3'''

press''' Enter'''
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;"| Type '''ipython3 '''and press '''Enter.'''

From here onwards, remember to press the '''Enter''' key after typing every command on the '''terminal'''.

|-
| style="background-color:#ffffff;border-top:0.5pt solid #000001;border-bottom:0.5pt solid #000001;border-left:0.5pt solid #000001;border-right:none;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;"| Type: '''num = int(input())'''

Enter number 4 and press '''Enter'''
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;"| Now let us check if an entered number is even or not.

Type, '''num '''''is equal to''''' int '''''inside brackets''''' input '''''open and close brackets''

Enter 4 and press '''Enter'''

|-
| style="background-color:#ffffff;border-top:0.5pt solid #000001;border-bottom:0.5pt solid #000001;border-left:0.5pt solid #000001;border-right:none;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;"| Type

'''if num % 2 == 0: print ('Even')else: print ('Odd')'''

Highlight the output

HIghlight the spaces
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;"| Type, '''if num '''''percentage''''' 2 '''''equal to equal to '''''0 '''''colon''

'''print '''''inside brackets inside single quotes '''''Even'''

Press backspace four times and type, '''else '''colon

'''print '''''inside brackets inside single quotes '''''Odd'''

Press''' Enter '''twice to get the output.

As expected, it displays '''Even''' as output.

Note that, the '''statements''' inside a '''code block''' are '''indented''' by 4 spaces automatically.

'''elif statement'''

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;"| Next we will see another '''conditional statement''' called '''elif'''.

All the syntax and rules for '''elif '''are same as '''if/else statements.'''

In '''if/else, '''only one condition is checked.

But in '''elif''' '''statement '''multiple conditions can be checked.

|-
| style="background-color:#ffffff;border-top:0.5pt solid #000001;border-bottom:0.5pt solid #000001;border-left:0.5pt solid #000001;border-right:none;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;"| Show Slide

'''if/elif Example'''

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;"| For example,

The first block of code is executed as soon as one of the conditions evaluates to '''True'''.

All the subsequent conditions in '''elif '''ladder are not checked.

The '''else''' '''block''' gets executed if all the '''conditions''' in '''elif '''ladder are evaluated to '''False'''.

|-
| style="background-color:#ffffff;border-top:0.5pt solid #000001;border-bottom:0.5pt solid #000001;border-left:0.5pt solid #000001;border-right:none;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;"| Type '''a = -3'''

'''if a > 0:'''

'''print ("positive")'''

'''<nowiki>elif a < 0:</nowiki>'''

'''print ("negative")'''

'''else:'''

'''print ("zero")'''

Highlight '''positive'''

Highlight '''negative'''

Highlight '''zero'''
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;"| Let us understand '''if/elif/else ladder '''with an example.

Type, '''a '''''is equal to minus''''' 3'''

We have a variable''' a''' which holds '''integer''' value as -3.

Type as shown.

This program will print''' '''

* '''"positive"''' if '''a''' is '''positive''',
* "'''negative'''" if it is '''negative''' or
* '''"zero"''' if it is''' 0'''.

Press '''Enter''' twice to see the output.

|-
| style="background-color:#ffffff;border-top:0.5pt solid #000001;border-bottom:0.5pt solid #000001;border-left:0.5pt solid #000001;border-right:none;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;"| Show Slide '''if/elif example'''

Highlight elif
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;"| We can also have any number of '''elif''' conditions within an '''if/elif/else statements'''.

For example, based on the type of user the corresponding operations are performed using '''elif'''.

Note that '''else block '''is optional in both '''if/else '''and''' if/elif/else statements'''.

|-

Ternary operator

syntax:

<nowiki>[A] if <condition> else [B]</nowiki>

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;"| Next let us learn about '''ternary''' operator.

Ternary operator allows to test a condition in a single line replacing the multiline''' if-else'''.

It can reduce the code size and increase the readability of the code.

Here is the syntax.

|-
| style="background-color:#ffffff;border-top:0.5pt solid #000001;border-bottom:0.5pt solid #000001;border-left:0.5pt solid #000001;border-right:none;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;"| Type, '''a = 4'''
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;"| Let us write a '''ternary conditional statement '''to find the largest of two numbers.

'''Type, a '''''is equal to''''' 4'''

|-
| style="background-color:#ffffff;border-top:0.5pt solid #000001;border-bottom:0.5pt solid #000001;border-left:0.5pt solid #000001;border-right:none;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;"| Type, '''b = 2'''
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;"| '''b '''''is equal to''''' 2'''

|-
| style="background-color:#ffffff;border-top:0.5pt solid #000001;border-bottom:0.5pt solid #000001;border-left:0.5pt solid #000001;border-right:none;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;"| Type, '''large_num = a if a > b else b'''
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;"| '''large '''''underscore '''''num '''''is equal to''''' a if a '''''greater than''''' b else b'''

|-
| style="background-color:#ffffff;border-top:0.5pt solid #000001;border-bottom:0.5pt solid #000001;border-left:0.5pt solid #000001;border-right:none;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;"| Type, '''print(large_num)'''

Pass statement

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;"| Next we will learn about '''pass statement'''.

The '''pass '''statement acts as a '''''null ''operation''' (i.e) nothing happens when it executes.

It works as a '''placeholder''' for a '''block''' of '''code'''.

It is used in a '''code block '''where actual '''code''' '''implementation''' is not known yet.

|-
| style="background-color:#ffffff;border-top:0.5pt solid #000001;border-bottom:0.5pt solid #000001;border-left:0.5pt solid #000001;border-right:none;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;"| Type '''a = 11'''
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;"| Let us understand the '''pass''' statement with an example.

Type '''a''' ''is equal to'' '''11'''

|-
| style="background-color:#ffffff;border-top:0.5pt solid #000001;border-bottom:0.5pt solid #000001;border-left:0.5pt solid #000001;border-right:none;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;"| Type,

'''if a%2 == 0: print(‘even’)else: pass'''
| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;"| Then type as shown.

If '''a''''' divided by '''''2''' equals to zero, '''if block''' is executed.

Else no operation is performed.

Press '''Enter''' key twice to get the output.

Here '''a''''' divided by '''''2''' is not 0.

So no operation is performed and nothing is displayed as output.

Summary

| style="background-color:#ffffff;border:0.5pt solid #000001;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;"| This brings us to the end of the tutorial.

Let us summarize.

In this tutorial, we have learnt the '''conditional statements''' such as,

* '''if/else statement'''
* '''if/elif/else statement'''
* '''Ternary conditional statement '''and
* '''Pass statement'''
