Python Variables

Creating Variables

Variables are containers for storing data values.

Unlike other programming languages, Python has no command for declaring a variable.

A variable is created the moment you first assign a value to it.

Example

x = 5

y = "John"

print(x)

print(y)

Variables do not need to be declared with any particular type and can even change type after they have been set.

Example

x = 4 # x is of type int

x = "Sally" # x is now of type str

print(x)

String variables can be declared either by using single or double quotes:

Example

x = "John"

# is the same as

x = 'John'
