Polymorphism is a fundamental concept in object-oriented programming (OOP) that allows objects to take on multiple forms. In Python, polymorphism can be achieved through interfaces, also known as abstract base classes (ABCs).

In this article, we will explore how interfaces enable polymorphic behavior in Python, providing clear explanations and practical examples to illustrate their importance in software development.

What are Interfaces (Abstract Base Classes)?

Interfaces, or abstract base classes (ABCs), serve as blueprints for classes, defining a set of methods that must be implemented by their subclasses. While Python does not support strict interface enforcement like some other languages, ABCs provide a way to define common behaviors and ensure consistency across different implementations.

Understanding Polymorphic Behavior with Interfaces

Polymorphism, a core principle of OOP, allows objects to exhibit different behaviors based on their specific class type. Interfaces facilitate polymorphic behavior by defining a common interface that multiple…
