Variables

Variable names:

• can only contain alpha-numeric characters and underscores (A-z, 0-9, and _ )
• cannot start with a number
• must start with a letter or the underscore character
• are case-sensitive (age, Age and AGE are three different variables)

Casting

• x = str(3) # x will be '3'
• y = int(3) # y will be 3
• z = float(3) # z will be 3.0

Get Type

• print(type(x))

*Single/Double quotes *Variables are case-sensitive:

• "a" will not overwrite "A"
