What are the techniques used in Python to achieve Polymorphic behavior?

 

Programming is like talking to computers using their own language, almost like having a superpower. You provide step-by-step instructions, and they follow along to make things happen.

Now, you might wonder why programming is so important. Well, think about all the technology around you - your smartphone, social media, and most things you use daily. They all rely on code, which tells the devices what to do. It's like the ultimate tool for making digital things work.

One of the most essential programming languages is Python. It's friendly, easy to understand, and very versatile. Python doesn't use confusing words or tricky rules. It focuses on being simple and straightforward for users.

There are several concepts and techniques in Python that you need to know and understand if you are new to the programming world. The concept of Polymorphic behavior is one of them.

This blog will introduce you to the concepts and techniques to achieve Polymorphism in Python. We will also delve into the concept of OpenCV in Python and its uses in Python programming.

So, let us dive into the vast ocean of Python programming and drink up the concepts of Polymorphism in Python and OpenCV in Python.

What is Polymorphism in Python?

Polymorphism in Python is a fundamental concept that implies that a single element within Python can exhibit various behaviors based on its context. This is similar to the versatility of a word, such as "express," that can serve different purposes based on different sentences. 

Although the sequence of letters remains constant, the meaning it imparts to the sentence varies significantly. Similarly, in polymorphic programming, a sole entity can assume distinct roles depending on the context.

Polymorphism allows for more flexible and generic code because you can write functions and methods that can work with various objects as long as they adhere to a common interface (in this case, having a speak method). 

This makes code more maintainable and extensible as new classes can be added. Polymorphism also removes the need to modify existing code if they follow the same interface.

Class and method polymorphism

Class and method polymorphism are two aspects of polymorphism in Python. They work similarly to other Object-oriented languages.

Class Polymorphism in Python: This form of polymorphism involves using inheritance and subtyping to create a hierarchy of classes. It allows objects of different classes derived from a common base class to be treated as objects of the base class. 

Simply put, you can use a subclass wherever you use an object of the superclass. Class polymorphism ensures that the methods or behaviours defined in the base class can be overridden in derived classes, allowing each subclass to provide its own implementation.

Method Polymorphism in Python: Method polymorphism is closely related to class polymorphism. It entails declaring a method in a base class. Then, the subclasses implement the same function in their own ways.
