What is an abstract class give an example?

Introduction to Python Abstract Classes In object-oriented programming, an abstract class is a class that cannot be instantiated . However, you can create classes that inherit from an abstract class. Typically, you use an abstract class to create a blueprint for other classes.

In Python, abstract base classes provide a blueprint for concrete classes . They don’t contain implementation. Instead, they provide an interface and make sure that derived concrete classes are properly implemented. Abstract base classes cannot be instantiated.

Abstract classes are essential to providing an abstraction to the code to make it reusable and extendable. For example, a Vehicle parent class with Truck and Motorbike inheriting from it is an abstraction that easily allows more vehicles to be added .

An abstract class can be considered as a blueprint for other classes . It allows you to create a set of methods that must be created within any child classes built from the abstract class. A class which contains one or more abstract methods is called an abstract class.19 Mar 2021
