Object Oriented Design

Operator overloading is a compile time polymorphism that allows us to extend the meaning of an operator to operate on a user-defined data type. The main advantage of operator overloading is that we can have different implementations of an operator based on the argument type. Here we will learn how to implement and overload various operators.

Abstraction is a process of exposing necessary functionality to external objects and hiding implementation details. This helps programmers to use complex logic without understanding its implementation. So one needs to know what code does, not how it does it. There are two types of abstraction in oop: data abstraction and control abstraction.

Abstraction, Encapsulation, Inheritance, and Polymorphism are four fundamental principles of object oriented programming. These oops principles provide advantages like modularity, code reusability, feature extensibility, data hiding, etc. In this blog, we will learn how the four main oop principles work together to make a well-designed application.

Modern software usually consists of millions of lines of code and operates on terabytes of data. So we need a way to organize a large code base to make it easier to understand, explain, reuse, extend and maintain. That's why we need object oriented programming (OOP). It has been one of the most important paradigms used in the last few decades.

Abstract Factory is a creational design pattern that helps in providing an interface for producing families of related objects (products) without specifying their concrete classes. It is a hierarchy of classes that encapsulate many possible “platforms” and provide an interface for the construction of a suite of products.

In Python, everything is an object which holds different properties and methods. Class is a blueprint that creates these objects. In this blog, we have explained fundamental oops concepts in python: 1) What are classes and objects? 2) How to use classes and objects? 3) Default classes examples in python 4) Abstraction, Inheritance and Polymorphism.
