Python Variables

Python Variables:

Variables are containers or memory pool for storing data values.
A variable is created when we assign a value to it.

Example 1:

x = 6 # x is of type int
x = "MANY" # x is now of type str

Example 2:

x = "pop"
# both are same 
x = 'pop'

Rules for Variables:

• A variable name must start only with a letter or the underscore character.
• A variable name cannot start with a number.
• A variable name can only contain alpha-numeric characters and underscores (A-Z, a-z, 0-9, and _ ).
• Variable names are case-sensitive (pop, Pop and POP are three different variables)

Note : Python allow to assign value to multiple variable in one line.

Example:

x, y, z = "Car", "Lemon", "Cherry"

Note:Python also allow to assign the same value to multiple variable in one line.

Example:

x = y = z = "Apple"
