What are Variables ?
A Python variable is a reserved memory location to store values. The value of variable can be changed at the run time. Python is not “statically typed”. We do not need to declare variables before using them, or declare their type. A variable is created the moment we first assign a value to it.

Variable naming rules :
 A variable name must start 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 ( var, VAR and Var are three different variables ).
 Can not use reserved words ( Keywords ) as the name for variables.

What are Datatypes ?
In computer science and computer programming, a data type or simply type is an attribute of data which tells the compiler or interpreter how the programmer intends to use the data.
