"""
there are some methods in python class
      Magic methods in Python are the special methods which add "magic" 
      to your class. Magic methods are not
      meant to be invoked directly by you, but the invocation happens
      internally from the class on a certain action.

"""
The below is example of overloading the arthematic methods like addition subtraction etc
whihc also returns a object of that class
