Why Python Is Object Oriented Programming Language?


Heather Bennett

Python is a widely-used programming language that has gained immense popularity in recent years. One of the reasons for its success is its object-oriented nature. In this article, we will explore why Python is considered an object-oriented programming language and how it utilizes this paradigm to its advantage.

What is Object-Oriented Programming?

Object-oriented programming (OOP) is a programming paradigm that revolves around the concept of objects. An object is an instance of a class, which can have properties (attributes) and behaviors (methods). OOP allows us to encapsulate data and functions together into reusable modules called classes.


Encapsulation is one of the fundamental principles of OOP. It refers to the bundling of data and methods within a class, such that they are not accessible outside the class unless explicitly defined. This concept promotes modular and organized code, making it easier to manage and maintain.


Inheritance is another key aspect of OOP. It allows classes to inherit properties and methods from other classes, forming a hierarchical relationship. In Python, inheritance is implemented through the use of base classes and derived classes.


Polymorphism is the ability of objects to take on many forms. It allows different classes to implement methods with the same name but with different functionality. This concept enables code reusability and flexibility in design.

Python’s Object-Oriented Features

Python fully supports OOP concepts like encapsulation, inheritance, and polymorphism. Let’s take a closer look at each of these features in Python:

  • Classes: In Python, we define classes using the class keyword. Classes act as blueprints for creating objects.
  • Attributes: Objects have attributes that store data associated with them. These attributes can be accessed using the dot notation.
  • Methods: Methods are functions defined within a class and operate on objects of that class. They can modify the object’s state or perform specific actions.
  • Constructor: Python provides a special method called the constructor, denoted by __init__().

    It is invoked automatically when an object is created and allows us to set initial values for attributes.

  • Inheritance: In Python, we can create derived classes by inheriting from base classes. The derived class inherits all the attributes and methods of the base class and can also override or extend them.
  • Polymorphism: Python supports polymorphism by allowing multiple classes to implement methods with the same name but different functionality. This provides flexibility in method calls based on the type of object.

Why Python Embraces OOP?

Python’s adoption of OOP has numerous benefits:

  • Code Reusability: OOP promotes code reusability due to features like inheritance and polymorphism. We can create generic classes that serve as templates for creating specialized classes, reducing code duplication.
  • Modularity: With encapsulation, we can create independent modules that interact with each other through well-defined interfaces.

    This enhances code modularity and maintainability.

  • Ease of Collaboration: OOP facilitates collaboration among developers working on large projects. Different team members can focus on different modules without interfering with each other’s work, thanks to encapsulation and clear interfaces.

In conclusion, Python’s embrace of object-oriented programming has contributed significantly to its success as a programming language. By incorporating key OOP concepts like encapsulation, inheritance, and polymorphism, Python offers a powerful and flexible way to organize and structure code. Whether you are a beginner or an experienced programmer, understanding and utilizing Python’s OOP features can greatly enhance your ability to write clean, modular, and reusable code.
