Here's an example of method overriding in Python 3:
The ElectricCar class also has its own attribute battery_size and method charge . Polymorphism is the ability of an object to take on multiple forms. In Python 3, polymorphism can be achieved through method overriding or method overloading.

Welcome to the fourth installment of our Python 3 Deep Dive series, where we explore the depths of the Python programming language. In this article, we'll dive into the world of Object-Oriented Programming (OOP) in Python 3. OOP is a fundamental concept in programming that allows you to create reusable code, model real-world objects, and write more maintainable and efficient software. What is Object-Oriented Programming (OOP)? Object-Oriented Programming (OOP) is a programming paradigm that revolves around the concept of objects and classes. In OOP, a program is designed as a collection of objects that interact with each other to achieve a specific goal. Each object represents a real-world entity, such as a car, a person, or a bank account, and has its own set of attributes (data) and methods (functions). Classes and Objects in Python 3 In Python 3, a class is a template that defines the properties and behavior of an object. A class is essentially a blueprint or a template that defines the characteristics of an object. An object, on the other hand, is an instance of a class, which has its own set of attributes and methods.
In Python 3, encapsulation can be achieved using private variables and methods, which are denoted by a double underscore prefix. Here's an example of method overriding in Python
my_car = Car("Toyota", "Corolla", 2015) This creates a new object called my_car from the Car class, with the specified attributes.
Method overriding is when a subclass provides a different implementation of a method that is already defined in its superclass. Here's an example of encapsulation in Python 3:
def area(self): return self.width ** 2 In this example, the Square class overrides the area method of the Rectangle class. Encapsulation is the concept of hiding the internal details of an object from the outside world and only exposing a public interface through which other objects can interact with it.
