The Four Pillars of OOP

These four principles help developers build maintainable, reusable, modular and extensible software.

Choose a pillar

Select one of the four pillars to explore its implementation.

Visual Class & Object Lab

Build a simple class, create multiple objects, assign different values and observe how each object maintains its own state.

A class defines the structure and behaviour. An object is an individual instance created from that class.

1. Define your class

Class name Attribute 1 name Attribute 2 name Method name

2. Create an object

Object name name value course value

Object memory inspector

Each object below has its own attribute values. Creating another object does not overwrite the previous one.

Build a class and create your first object.

Class definition generated from your lab

class Student:
    def __init__(self, name, course):
        self.name = name
        self.course = course

    def introduce(self):
        return f"{self.name} is learning {self.course}"
