Python is a versatile and powerful programming language that has gained immense popularity due to its simplicity, readability, and vast ecosystem of libraries and frameworks. However, as your codebase grows, maintaining code quality and catching type-related errors can become increasingly challenging.

This is where polymorphism and static type checking come into play, providing developers with tools to write cleaner, more maintainable code.

Polymorphism in Python

Polymorphism is a fundamental concept in object-oriented programming (OOP) that allows objects of different classes to be treated as objects of a common superclass. In Python, polymorphism is achieved through method overriding and duck typing.

Method Overriding

Method overriding is a form of polymorphism where a subclass provides its own implementation of a method that is already defined in its superclass. This allows the subclass to inherit the behavior of the superclass while customizing it to meet its specific needs.

class Animal:
    def make_sound(self):
        print("The animal makes a sound.")
