Welcome to Dr. Sourav Sir’s Classes! In today’s Python tutorial, we dive into a very insightful and often misunderstood topic in object-oriented programming—What is a Class Method Constructor in Python?

If you're confused about the difference between instance methods, class methods, and how constructors like __init__ differ from @classmethod constructors—this is the video for you.

We’ll help you understand how to build alternative constructors using the @classmethod decorator, why it's useful, and how to implement it practically using a clean, real-world example.

???? What You’ll Learn in This Video

✅ What is a class method in Python?

✅ Syntax and usage of @classmethod

✅ Differences between instance method and class method

✅ How to use cls instead of self

✅ Building alternate constructors using class methods

✅ Use cases of classmethod in factory design and data parsing

???? Concept Highlight

cls refers to the class itself

Allows creation of new objects using alternative formats (e.g., strings)

Useful in data ingestion and factory methods

????‍???? Ideal For:

Python learners preparing for technical interviews

Students in CUET PG, UGC NET, ISI, IIT JAM

BCA/MCA/CS undergrads and academic project developers

Anyone trying to master Python OOP beyond basics
