🐍🚀 *Abstract Base Classes (ABC) in Python | Advanced Python OOP Concepts Explained*

Welcome to another Advanced Python Programming tutorial! 🔥

In this video, we will explore one of the most important Object-Oriented Programming concepts in Python:

🎯 *Abstract Base Classes (ABC)*

Abstract Base Classes help developers create blueprints for classes and enforce rules that child classes must follow. They are widely used in large-scale applications to improve code consistency, maintainability, and software architecture.

If you're learning Advanced Python, preparing for interviews, or building professional software applications, understanding ABC is an essential skill.

📚 What is an Abstract Base Class?

An *Abstract Base Class (ABC)* is a special class that cannot be instantiated directly.

It acts as a blueprint for other classes and ensures that certain methods are implemented in all child classes.

Example Concept:

```python
from abc import ABC, abstractmethod

class Vehicle(ABC):

@abstractmethod
def start(self):
pass
```

Any class inheriting from `Vehicle` must implement the `start()` method.
