🧱 Object-Oriented Python

Classes & Objects

Define your own types with state and behavior.

A class is a blueprint. An *object* is an instance of that blueprint. Use class to define one and __init__ to set up new instances.

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

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

d = Dog("Rex")
print(d.bark())

self is the instance itself — always the first parameter of an instance method.
