Python Tutorial 8.1 - Classes & Objects

Welcome to the “Classes & Objects” tutorial!

Overview

Classes are blueprints for creating objects (instances). Objects bundle data (attributes) and behavior (methods).

Defining a Class

class Dog:
    def __init__(self, name, age):
        self.name = name
        self.age = age

    def bark(self):
        return f"{self.name} says woof!"

Creating Instances

fido = Dog("Fido", 3)
print(fido.name)    # Fido
print(fido.bark())  # Fido says woof!

Key Takeaways

• Use class keyword to define a class.
• self refers to the instance.
• Instantiate with ClassName(...).

Happy coding!
