Welcome to Lecture 73 of our Python Mastery Series 🔥
In this lecture, we solve a practical OOP problem based on an Inventory Management System.
We create an Item Class that stores item details and demonstrates how constructors (__init__) can work with both required and optional parameters.
This question is an excellent practice for understanding how real-world objects are created in Python applications.
📌 Topics Covered
✅ Classes & Objects
✅ Constructor (__init__)
✅ Required Parameters
✅ Optional Parameters
✅ Default Arguments
✅ Instance Attributes
✅ Object Initialization
✅ Inventory System Example
✅ OOP Practice Question
✅ Theory + Practical Demonstration
