Variables
An area in memory used to store a value the program will use.
The value is likely to change
Here are some examples in Python
name = "Dave"                      - Text 
health = 100                           - Integer
Player_dead = False                  - Boolean  (True/False)

Inputs
We often use variables to store inputs from the user
In Python we use input
input ("Question the user will see as a prompt")
So to store a name we would use:
name = input ("What is your name  ? -->  ")

Slide 16 - Slide

filmpref = input("What kind of films do you like? ")

Label the correct parts of the code with the symbols.
Click the icon for more information  
This the the variable name given to a piece of information
This will allow the user to enter information that will be saved to the variable. 
This is a string, we place a question inside so the user knows which information to enter.
