In a sense, classes serve as a template to create objects. They provide the characteristics and operations that the objects will employ. Suppose a class is a prototype of a building.In Python, a superclass or base class is defined just like a regular class using the class keyword. The superclass contains attributes and methods that are common to a group of related classes: class Vehicle: """A superclass base class for all vehicles""" def __init__ (self, make, model, fuel):A Class is like an object constructor, or a "blueprint" for creating objects.
