Area of a Square with Constructor in Python | #Python #Constructor #OOP #SquareArea

Welcome to Dr. Sourav Sir’s Classes, your trusted platform for mastering Python and cracking technical concepts with clarity! In this video titled "Area of a Square with Constructor in Python", we explore how to use a constructor (__init__ method) to calculate the area of a square using a simple, clean, and beginner-friendly Python class example.

This video is a part of our Python OOP (Object-Oriented Programming) series and is designed for both absolute beginners and students preparing for technical exams, coding interviews, or school/college assignments.

???? What You’ll Learn in This Video

✅ What is a constructor (__init__) in Python

✅ How to define a class for a geometric shape (square)

✅ How to initialize object properties using constructor parameters

✅ How to calculate area of a square using Python methods

✅ Real-world usage of OOP concepts with practical code

✅ Syntax clarity, logic building, and best coding practices

✅ Common mistakes and how to avoid them

???? Mathematics Behind the Code

The formula used is:
Area of a Square = side × side
This is implemented using a method inside a class, and the side length is passed via a parameterized constructor to maintain modularity and reusability.

???? Concept Breakdown:

__init__ constructor assigns the side value to the object.

area() method performs the square calculation.

Object s is created with side length 9.

The result is printed using the method.
