Python is an Object-Oriented Programming Language. That means that Python implements a programming paradigm based on “objects,” where every “object” can store some data and the code to modify it. Class is a description of the “object” that defines attributes that characterize the object and the methods that this object implements. The existing class from which the child class inherits is known as the superclass (parent or base class).
