Classes

Introduction to Object-Oriented Programming — learn how to create classes and objects.

Classes are blueprints for creating objects — the foundation of OOP in Python.

Creating a Class

class Dog:
    species = "Canis familiaris"  # class attribute

    def bark(self):
        print("Woof!")

my_dog = Dog()
my_dog.bark()  # Woof!

Why Use Classes?

  • Encapsulation — Group related data and behavior
  • Reusability — Create multiple instances from one blueprint
  • Organization — Structure complex programs logically
