Class is a blueprint or framework or template which can be used repeatedly. This is part of the concept known as DRY ( Don't Repeat Yourself ) in Python
Standard Template ( method )
One standard format is used to give each student one mark sheet.

Methods are available to the objects of the class.
Creating object.
Objects can be created by using class name.
Alex=student_kit('Alex','A')
Here in above code Alex is the object created for the class student_kit().
Initialization of the object
While creating the object, class runs one default function __init__(). This function initialize the
