| + | |- | ||
| + | ||01.36 | ||
| + | || Boolean values | ||
| + | |- | ||
| + | ||01.38 | ||
| + | ||Now we will see where to store numbers | ||
| + | |||
| + | |- | ||
| + | ||01.42 | ||

| + | |||
| + | |- | ||
| + | ||01.49 | ||
| + | ||Variables | ||
| + | |- | ||
| + | ||01.50 | ||
| + | ||I will zoom the program text for clear view. | ||
| + | |- | ||
| + | ||01.54 | ||
| + | ||First let's look at variables. | ||
| + | |||
| + | |- | ||
| + | ||01.57 | ||
| + | ||Variables are words that start with ‘$’ sign, for example $a. | ||
| + | |||
| + | |- | ||
| + | || 02.04 | ||
| + | ||In the editor they are highlighted in '''purple''' color. | ||
| + | |||
| + | |- | ||
| + | ||02.09 | ||
| + | ||Using the assignment, equal to (=), a variable is given its content. | ||
| + | |||
| + | |- | ||
| + | ||02.14 | ||
| + | ||Variables can contain numbers '''$a=100'''. | ||
| + | |||
| + | |- | ||
| + | ||02.20 | ||
| + | ||strings '''$a=hello''' or | ||
| + | |||
| + | |- | ||
| + | ||02.25 | ||
| + | ||boolean values that is true or false '''$a=true''' | ||
| + | |||
| + | |- | ||
| + | ||02.32 | ||
| + | ||Variable keeps the content until program finishes execution or until it is reassigned to something else. | ||
| + | |||
| + | |- | ||
| + | ||02.41 | ||
| + | ||For example, consider the code. | ||
| + | |||
| + | |- | ||
| + | ||02.44 | ||
| + | ||Let us type,'''$a = 2004''' | ||
| + | |||
| + | |- | ||
| + | ||02.50 | ||
| + | ||'''$b = 25''' | ||
| + | |||
| + | |- | ||
| + | ||02.55 | ||
| + | ||'''print $a + $b''' | ||
| + | |- | ||
| + | ||03.01 | ||
| + | ||Variable 'a' is assigned a value ''' 2004.''' | ||
| + | |||
| + | |- | ||
| + | ||03.06 | ||

| + | ||Value '''2029''' is displayed on the canvas | ||
| + | |- | ||
| + | ||03.40 | ||
| + | ||Let us next see the Mathematical Operators. | ||
| + | |||
| + | |- | ||
| + | ||03.44 | ||
| + | ||Mathematical operators include, | ||
| + | |||
| + | * '''+''' (Addition) | ||
| + | |||
| + | * '''-''' (Subtraction) | ||
| + | |||
| + | * '''*''' (Multiplcation) and | ||
| + | |||
| + | * '''/''' (Division) | ||
| + | |- | ||
| + | ||03.53 | ||
| + | || I will clear the current code from editor and type '''clear''' command and '''RUN''' to clean the canvas | ||
| + | |- | ||
| + | ||04.01 | ||
| + | ||I already have a program in a text editor. | ||
| + | |- | ||
| + | ||04.05 | ||
| + | ||I will Explain the code now | ||
| + | |- | ||
| + | ||04.08 | ||
| + | ||'''“reset”''' command sets Turtle to its '''default''' position | ||

| + | |- | ||
| + | ||05.03 | ||
| + | ||Pause the tutorial and type the program into''' KTurtle''' editor. | ||
| + | |||
| + | |- | ||
| + | ||05.08 | ||
| + | ||Resume the tutorial after typing the program | ||
| + | |- | ||
| + | ||05.13 | ||
| + | ||Let us click on '''Run''' button to run the program | ||
| + | |||
| + | |- | ||
| + | ||05.17 | ||
| + | ||Command which is getting executed is highlighted on the editor. | ||
| + | |||
| + | |- | ||
| + | ||05.22 | ||
| + | ||'''Turtle''' displays the values on the canvas at the specified positions. | ||
| + | |- | ||
| + | ||05.34 | ||
| + | ||Let us consider a simple example for using '''comparison operator''' . | ||
| + | |||
| + | |||
| + | |- | ||
| + | || 05.41 | ||
| + | || I will clear the current code from editor and type '''clear''' command and '''RUN''' to clean the canvas | ||
| + | |- | ||
| + | || 05.49 | ||
| + | ||I will zoom the progrm text to have clear view | ||
| + | |- | ||
| + | || 05.53 | ||
| + | ||Let's type | ||
| + | |||
| + | |- | ||
| + | ||05.55 | ||
| + | ||'''$answer = 10 > 3''' | ||
| + | |||
| + | |- | ||

| + | |- | ||
| + | ||06.14 | ||
| + | ||The result of this comparison, the '''boolean value true''' is stored in the | ||
| + | |||
| + | |- | ||
| + | ||06.19 | ||
| + | ||variable '''$answer''' and the value '''true''' is displayed on the canvas. | ||
| + | |- | ||
| + | || 06.27 | ||
| + | ||Let's run the code now | ||
| + | |||
| + | |- | ||
| + | ||06.29 | ||
| + | ||'''Turtle''' displays '''Boolean value true''' on the canvas. | ||
| + | |- | ||
| + | ||06.34 | ||
| + | ||Now lets see how Strings work in this application – | ||
| + | |||
| + | |- | ||
| + | ||06.39 | ||
| + | ||Strings can be put in variables like numbers | ||
| + | |||
| + | |- | ||
| + | ||06.43 | ||
| + | ||Strings cannot be used in mathematical or comparison operators | ||
| + | |||
| + | |- | ||
| + | ||06.49 | ||
| + | ||Strings are highlighted in red color | ||
| + | |||
| + | |- | ||
| + | ||06.53 | ||
| + | ||KTurtle identifies a line in double quotes as a string | ||
| + | |- | ||
| + | || 07.00 | ||
| + | ||I will clear the current code from editor.type '''clear''' command and '''Run''' to clean the canvas | ||
| + | |- | ||
| + | || 07.08 | ||
| + | ||Now I will explain about Boolean values. | ||
| + | |||
| + | |- | ||
| + | ||07.11 | ||
| + | ||There are only two '''boolean''' values: '''true''' and '''false.''' | ||
| + | |- | ||
| + | ||07.16 | ||
| + | ||For example Let's type the code | ||
| + | |||
| + | |- | ||
| + | ||07.20 | ||
| + | ||'''$answer = 7<5''' | ||
| + | |||
| + | |- | ||
| + | ||07.28 | ||
| + | ||'''print $answer''' | ||
| + | |||
| + | |- | ||
| + | ||07.34 | ||
| + | ||'''Boolean value false''' is assigned to variable''' $answer''' because 7 is greater than 5 | ||
| + | |- | ||
| + | || 07.43 | ||
| + | ||Let's Run the code now | ||
| + | |||
| + | |- | ||
| + | ||07.47 | ||
| + | ||'''Turtle''' diplays '''Boolean''' value '''false''' on the canvas. | ||
| + | |- | ||
| + | || 07.51 | ||
| + | ||Let's next learn about “if-else” conditon. | ||
| + | |||
| + | |- | ||
| + | ||07.56 | ||
| + | ||‘if’ condition is executed only if the '''boolean''' value evaluates ‘true’ | ||
| + | |||
| + | |- | ||
| + | ||08.03 | ||
| + | ||‘else’ condition is executed only if the ‘if’ condition is ‘false’ . | ||
| + | |- | ||
| + | || 08.09 | ||
| + | ||I will clear the current code from editor.type '''clear''' command and '''Run''' to clean the canvas | ||
| + | |- | ||
| + | ||08.17 | ||
| + | ||I already have a code in a text file. | ||
| + | |- | ||
| + | || 08.21 | ||
| + | ||This code compares numbers 4 , 5 and 6 and displays the results accordingly on the canvas. | ||
| + | |- | ||
| + | ||08.30 | ||
| + | ||I will copy the code from text editor and paste it into '''KTurtle''' editor. | ||
| + | |||
| + | |- | ||
| + | ||08.36 | ||
| + | ||Pause the tutorial and type the program into your '''KTurtle''' editor. | ||
| + | |||
| + | |- | ||
| + | ||08.42 | ||
| + | ||Resume the tutorial after typing the program | ||
| + | |- | ||
| + | || 08.46 | ||
| + | ||Let's Run the code now | ||
| + | |||
| + | |- | ||
| + | ||08.49 | ||
| + | ||the '''Turtle''' has compared the values 4 and 5. | ||
| + | |||
| + | |- | ||
| + | ||08.53 | ||
| + | ||and has displayed the result 4 is smaller than 6 on the canvas . | ||
| + | |- | ||
| + | ||09.00 | ||
| + | ||With this we come to the end of this tutorial. | ||

| 00.01 | Hello everybody. |
| 00.02 | Welcome to this tutorial on Grammar of TurtleScript in KTurtle. |
| 00.08 | In this tutorial, we will learn about |
| 00.11 | Grammar of Turtle script and 'if'-'else' condition |
| 00.16 | To record this tutorial I am using, Ubuntu Linux OS version. 12.04. KTurtle version. 0.8.1 beta. |
| 00.29 | We assume that you have basic working knowledge of KTurtle |
| 00.35 | If not, for relevant tutorials, please visit our website. http://spoken-tutorial.org |
| 00.40 | Let's open a new KTurtle Application. |
| 00.43 | Click on Dash home. |
| 00.45 | In the Search bar, type KTurtle. |
| 00.49 | Click on the KTurtle icon. |
| 00.52 | We can also open KTurtle using Terminal. |
| 00.56 | Press CTRL+ALT+T simultaneously to open the Terminal. |
| 01.01 | Type KTurtle and press enter to open the KTurtle Application. |
| 01.08 | Let's first look at TurtleScript |
| 01.11 | TurtleScript is a programming language |
| 01.15 | It has different types of words and symbols used for various purposes |
| 01.21 | It instructs Turtle what to do |
| 01.25 | Grammar of TurtleScript in KTurtle includes- |
| 01.30 | Comments |
| 01.31 | Commands |
| 01.32 | Numbers |
| 01.33 | Strings |
| 01.34 | Variables and |
| 01.36 | Boolean values |
| 01.38 | Now we will see where to store numbers |
| 01.42 | Numbers can be stored in |
| 01.44 | Mathematical operators |
| 01.46 | Comparison operators and |
| 01.49 | Variables |
| 01.50 | I will zoom the program text for clear view. |
| 01.54 | First let's look at variables. |
| 01.57 | Variables are words that start with ‘$’ sign, for example $a. |
| 02.04 | In the editor they are highlighted in purple color. |
| 02.09 | Using the assignment, equal to (=), a variable is given its content. |
| 02.14 | Variables can contain numbers $a=100. |
| 02.20 | strings $a=hello or |
| 02.25 | boolean values that is true or false $a=true |
| 02.32 | Variable keeps the content until program finishes execution or until it is reassigned to something else. |
| 02.41 | For example, consider the code. |
| 02.44 | Let us type,$a = 2004 |
| 02.50 | $b = 25 |
| 02.55 | print $a + $b |
| 03.01 | Variable 'a' is assigned a value 2004. |
| 03.06 | Variable 'b' is assigned a value 25 |
| 03.10 | print command, commands Turtle to write something on the canvas. |
| 03.15 | print command, takes numbers and strings as input. |
| 03.19 | print $a + $b commands Turtle to add two values and display them on the canvas. |
| 03.29 | Let's Run the code in slow speed. |
| 03.34 | Value 2029 is displayed on the canvas |
| 03.40 | Let us next see the Mathematical Operators. |
| 03.44 | Mathematical operators include,
|
| 03.53 | I will clear the current code from editor and type clear command and RUN to clean the canvas |
| 04.01 | I already have a program in a text editor. |
| 04.05 | I will Explain the code now |
| 04.08 | “reset” command sets Turtle to its default position |
| 04.12 | canvassize 200,200 fixes the width and height of the canvas to 200 pixels each. |
| 04.22 | value 1+1 is assigned to the variable $add, |
| 04.26 | Value 20-5 is assigned to variable $subtract, |
| 04.31 | value 15 * 2 is be assigned to the variable $multiply. |
| 04.36 | 30/30 is assigned to the variable $divide. |
| 04.40 | go 10,10 commands to Turtle to go 10 pixels left of canvas and 10 pixels from top of canvas |
| 04.52 | print command displays the varible on the canvas |
| 04.56 | I will copy the code from text editor and paste it into KTurtle editor. |
| 05.03 | Pause the tutorial and type the program into KTurtle editor. |
| 05.08 | Resume the tutorial after typing the program |
| 05.13 | Let us click on Run button to run the program |
| 05.17 | Command which is getting executed is highlighted on the editor. |
| 05.22 | Turtle displays the values on the canvas at the specified positions. |
| 05.34 | Let us consider a simple example for using comparison operator .
|
| 05.41 | I will clear the current code from editor and type clear command and RUN to clean the canvas |
| 05.49 | I will zoom the progrm text to have clear view |
| 05.53 | Let's type |
| 05.55 | $answer = 10 > 3 |
| 06.03 | print $answer |
| 06.09 | Here 10 is compared to 3 with the ’greater than’ operator. |
| 06.14 | The result of this comparison, the boolean value true is stored in the |
| 06.19 | variable $answer and the value true is displayed on the canvas. |
| 06.27 | Let's run the code now |
| 06.29 | Turtle displays Boolean value true on the canvas. |
| 06.34 | Now lets see how Strings work in this application – |
| 06.39 | Strings can be put in variables like numbers |
| 06.43 | Strings cannot be used in mathematical or comparison operators |
| 06.49 | Strings are highlighted in red color |
| 06.53 | KTurtle identifies a line in double quotes as a string |
| 07.00 | I will clear the current code from editor.type clear command and Run to clean the canvas |
| 07.08 | Now I will explain about Boolean values. |
| 07.11 | There are only two boolean values: true and false. |
| 07.16 | For example Let's type the code |
| 07.20 | $answer = 7<5 |
| 07.28 | print $answer |
| 07.34 | Boolean value false is assigned to variable $answer because 7 is greater than 5 |
| 07.43 | Let's Run the code now |
| 07.47 | Turtle diplays Boolean value false on the canvas. |
| 07.51 | Let's next learn about “if-else” conditon. |
| 07.56 | ‘if’ condition is executed only if the boolean value evaluates ‘true’ |
| 08.03 | ‘else’ condition is executed only if the ‘if’ condition is ‘false’ . |
| 08.09 | I will clear the current code from editor.type clear command and Run to clean the canvas |
| 08.17 | I already have a code in a text file. |
| 08.21 | This code compares numbers 4 , 5 and 6 and displays the results accordingly on the canvas. |
| 08.30 | I will copy the code from text editor and paste it into KTurtle editor. |
| 08.36 | Pause the tutorial and type the program into your KTurtle editor. |
| 08.42 | Resume the tutorial after typing the program |
| 08.46 | Let's Run the code now |
| 08.49 | the Turtle has compared the values 4 and 5. |
| 08.53 | and has displayed the result 4 is smaller than 6 on the canvas . |
| 09.00 | With this we come to the end of this tutorial. |
| 09.05 | Let's summarize. |
| 09.07 | In this tutorial, we have learnt about |
| 09.11 | Grammar of Turtle script and |
| 09.14 | ‘if-else’ condition |
| 09.17 | Now to the assignment part. |
| 09.19 | Solve an equation using |
| 09.22 | if - else condition |
| 09.24 | Mathematical and comparision operators |
| 09.27 | Display the results using “print” and “go” commands. |
| 09.33 | To solve the assignment |
| 09.35 | Choose any four random numbers |
| 09.38 | Multiply two sets of random numbers |
| 09.42 | Compare the results using the comparison operators |
| 09.46 | Display both the results |
| 09.49 | Display greater result at the center of the canvas |
| 09.54 | You can choose any equation which you like. |
