Welcome to the advanced OOP (Object-Oriented Programming) tutorial! This guide dives deeper into Python's object-oriented features, including inheritance, polymorphism, encapsulation, and abstraction. Let's explore these concepts with practical examples.

📚 Core OOP Principles

  1. Class & Object
    A class is a blueprint for creating objects.

    Class_Diagram
    Example: ```python class Animal: def speak(self): pass ```

  2. Inheritance
    Enables new classes to inherit properties from existing ones.

    Inheritance_Hierarchy
    Example: ```python class Dog(Animal): def speak(self): return "Woof!" ```

  3. Polymorphism
    Allows objects of different classes to be treated as objects of a common superclass.
    🐾 Use super() to call parent class methods.

  4. Encapsulation
    Bundles data and methods within a class.
    🔒 Use private variables with double underscores: __attribute.

  5. Abstraction
    Hides complex implementation details.
    🧠 Use abstract classes with abc module.

🧪 Practical Example: Building a Game Character System

from abc import ABC, abstractmethod

class Character(ABC):
    @abstractmethod
    def attack(self):
        pass

class Warrior(Character):
    def attack(self):
        return "Swinging a sword!"

class Mage(Character):
    def attack(self):
        return "Casting a spell!"
