Python Polymorphism

What is Polymorphism?

Polymorphism is a core concept in object-oriented programming that allows objects of different classes to be treated as objects of a common superclass. It enables a single function or method to work in different ways depending on the object it is acting upon. This flexibility allows for more generic and reusable code.

Polymorphism in Python

In Python, polymorphism is typically achieved through method overriding and duck typing. Python's dynamic nature allows methods of the same name to behave differently based on the object calling them, without any strict type checks.

Example of Method Overriding

Method overriding allows a subclass to provide a specific implementation of a method that is already defined in its superclass. This is a common way to achieve polymorphism in Python.

Consider the following example:

Duck Typing in Python

Duck typing is a concept related to polymorphism where the type or class of an object is less important than the methods it defines. If an object implements the behavior expected by a method, it can be used regardless of its actual type.

Here's an example:

Benefits of Using Polymorphism

• Code Reusability: Write more generic and reusable code by using common interfaces or superclasses.
• Flexibility and Extensibility: Add new classes and functionalities with minimal changes to existing code.
• Simplified Code Maintenance: Simplify code maintenance by organizing and managing complex systems through unified interfaces.
