What is a boolean?
A boolean is a variable that is either True or False. We say the datatype of a variable can be booelan.
You can think of it like a light switch, its either on or off.
To define a boolean in Python we simply type:
light = FALSE
If you want to set it to on, you would type:
light = TRUE
You can also type:
light = 0
which is equivalent to FALSE. Likewise you can write
light = 1
which is the same as TRUE.
