Python classes are fundamental for object-oriented programming (OOP), allowing you to structure code with reusable components 🧱. Here's a quick overview:

What is a Class?

A class is a blueprint for creating objects. It defines properties (data) and methods (functions) that the objects will have.

Class Structure

Example:

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

    def bark(self):  # Method
        return f"{self.name} says: Woof!"

Key Concepts

  • Constructor (__init__): Initializes object attributes 🐾
  • Methods: Define behaviors, e.g., bark(), eat()
  • Attributes: Store data, e.g., name, age
