Introduction So far, you have learned how to: Create classes and objects Store data using attributes Write methods that change an object’s state In this lesson, we will take the next step. Instead of using methods on their own, you will learn how: Multiple methods can work together An object can behave like a small

Introduction In the previous lesson, you learned how to: Create methods inside a class Use self to access object data Call methods on different objects So far, our methods have only displayed information. In this lesson, you’ll learn how methods can also change the data inside an object. You will learn how to: Define multiple

Introduction So far, you’ve learned how to: Create classes Use __init__ to store data Use self to give each object its own attributes In this lesson, you’ll learn how to: Define methods inside a class Use self to access object data inside methods Call methods on objects Methods allow objects to do things, not just

Introduction In the previous lesson, you learned how to create a class and make objects from it. However, all objects created from the class shared the same data. In real programs, this is rarely what we want. In this lesson, you will learn how to: Use the constructor method (__init__) to set up objects properly.

Introduction As programs become larger and more complex, organising code clearly and efficiently becomes increasingly important. In earlier Python programs, we often use variables and functions to store data and perform actions. While this works well for small programs, it can quickly become difficult to manage as the program grows. This page introduces Object-Oriented Programming
