What is a Variable?

Think of it as a box with a label on it and you can store data in it. e.g.

cupboard = "cake"

In this example, my variable is called cupboard and in it, i am storing cake

Picture

Test yourself

Below are some more examples of using variables. Ask yourself, "What is the name of the variable?" and "What is the value it is storing?" Goodluck.
Wheelybin = "recycling"
The variable is called "Wheelybin" and it is storing the value "Recycling"
Healthpercentage = 100
The variable is called "HealthPercentge" and it is storing the value 100
married = true
The variable is called "Married" and it is storing the value True

Python challenge - Displaying the value of a variable

​Enter the following code in a Python code editor then press "F5" then "Enter"
Picture
When you run the code, what will it display on the screen?

Python challenge - Displaying the value of two variables

​Enter the following code in a Python code editor then press "F5" then "Enter"
Picture
When you run the code, what will it display on the screen?

​Python challenge - Multiplying the values of two variables

​Enter the following code in a Python code editor then press "F5" then "Enter"
Picture
When you run the code, what will it display on the screen?

​Python challenge - Multiplying by variable name

​Enter the following code in a Python code editor then press "F5" then "Enter"
Picture
When you run the code, what will it display on the screen?

​Python challenge - Changing the value in a variable

​Enter the following code in a Python code editor then press "F5" then "Enter"
