What Is OOP?

Object-oriented programming is a way of organizing code around objects and classes.

It helps us model real-world things in a structured way.

What Is a Class?

A class is a blueprint or model used to create objects.

It does not occupy memory by itself; memory is allocated only when an object is created from it.

What Is an Object?

An object is a real instance created from a class blueprint.

Every object gets its own copy of the instance variables declared inside the class.

🐍Code Cell
1s = Student()
Output
No output captured.
