What are variables?

A variable is the one which holds the values.

Syntax:
    VariableName = values
Example:
    variable = 1
    print variable
Output:
    1
Integer Variable can be used like this in python...eg: variable =1

Note Worthy: Like C, C++, Java you don't have to declare the data type of the variable in python. The variable in Python is itself acts as datatype based on the values it holds. 

How to store the Strings in variables?

Its the same as the Integer Variable usage, but the minor change is ....

The String should be surrounded with quotes ..

Syntax:
   StringVariableName = "String values goes here"
Example:
   String="Dharani"
   print String
Output:
   Dharani

Note Worthy: Some times you might get a doubt that...whether we should ' '  or " " for string .Chill!...No worries in Python..You can use both..It works..
