Python Object Oriented programming (OOP)

With examples, you will master the fundamentals of Python’s Object-Oriented Programming (OOP) and how it works in this lesson.

What is Object-Oriented Programming (OOP)?

A program can utilize an object constructed using the object-oriented programming (OOP) technique, which mixes data with the instructions to operate the object.

An object can be anything. It can possess the following two qualities:

  • Attributes
  • Action

Here’s an illustration:

A Person is an object because it has the following qualities:

  • Name, age, address, and color as attributes
  • Running, talking, breathing, and walking as actions

In other words, object-oriented programming is a method for simulating actual, physical objects like vehicles and relationships between them, such as those between organizations and their employees, students and professors, and so on. OOP depicts real-world items as software objects with data attached and the ability to carry out specific actions.

Python is a multi-paradigm programming language and facilitates many programming methods. Object-oriented programming and procedural programming are one of them. Procedural programming represents the data and determines how the program is organized. Creating objects is one of the common ways to tackle a programming challenge. The term “object-oriented programming” refers to this (OOP). Object-oriented programming offers ideas that facilitate translating complex real-world systems into controllable software solutions.

The main idea is that objects are at the core of Python’s object-oriented programming. Python’s OOP philosophy emphasizes writing reusable code. Another name for this idea is DRY (Don’t Repeat Yourself).

Object-oriented programming (OOPs) uses objects and classes in the Python programming style. It seeks to incorporate real-world programming concepts like inheritance, polymorphism, encapsulation, etc. The fundamental idea behind OOPs is to unite the data and its functions so that no other piece of code can access it.

Object-oriented programming’s characteristics

Object-oriented programming’s primary characteristics include:

  • Improved programming philosophies
  • Emphasis on access and security
  • Elimination of duplicate codes
  • Real-world application is accurately modeled.

Advantages of OOP over procedure-oriented programming (POP)

OOPs have the following advantages over procedure-oriented programming (POP): In comparison to POP, OOPs will make designing and maintaining software simpler. When the project size increases along with the code, it will be challenging for the procedure-oriented programming language. Compared to OOPs, the procedure-oriented programming language is less efficient. In contrast to procedure-oriented programming languages, in which you may access code from anywhere, OOPs provide data hiding. This technique is thus dangerous. Effectively simulating the real-world scenario is more straightforward than using OOPs. Therefore, the OOP approach is best for resolving real-world issues.
