Python 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.
y = "John"
Variables do not need to be declared with any particular type and can even change type after they have been set.
x = "Sally" # x is now of type str
String variables can be declared either by using single or double quotes:
# is the same as
x = 'John'
