Python Variables

A variables is a location in memory used to store value.they are given unique names to differentiate between different memory location. the rules for writing a variable name is same as the rules for writing identifiers in python.

In python do not need to declare a variable before using it.in python,we simply assign a value to a variable and it will exist.we don't even have to declare the type of the variable.this is handled internally according to the type of value we assign the variable.

Example

>>> a = 10;
>>> print(a);

Variable Names

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)
