Unlike other programming language, Declaring variable in python is very easy, In python variable is created at the moment you assign a value to it. And variable can be of any data type.

Rules for Variable Names
A variable can have a short name (like x and y) or a more descriptive name (age, name, sum, volume). Rules for Python variables:
- A variable name must always 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, 0-9, and _ )
- Variable names are case-sensitive (age, Age and AGE are three different variables)
In Python you can use + operator to combine to variable names of same data type.
