From abc import abc abstractmethod class abstractclassexample abc. How abstract base classes work. The shape class has area method decorated by abstractmethod.

Almost everything in python is an object with its properties and methods. Python comes with a module which provides the base for defining abstract base classes abc and that module name is abc. A rectangle class now uses above shape class as its parent and implementing the abstract area method.

Following example defines shape class as an abstract base class using abcmeta. A class is like an object constructor or a blueprint for creating objects. 1 starting that work or 2 validating it.
