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.
A variable can have a short name (like x and y) or a more descriptive name (age, carname, total_volume). Rules for Python variables:
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, 0-9, and _ )
Variable names are case-sensitive (age, Age and AGE are three different variables)

The Python print statement is often used to output variables.
To combine both text and a variable, Python uses the + character:
