Summary  
This chapter introduces class inheritance in object-oriented programming, showing how subclasses inherit properties and methods from superclasses to promote code reuse and establish logical “is-a” relationships. It also explains how inheritance enables extensibility and polymorphism.

General domain of usage  
Modeling hierarchies in transportation systems (e.g., Vehicle, Car, Bicycle)

**Inheritance** is a core OOP principle that allows a new class to inherit properties and methods from an existing class. It promotes code reuse and logical structure. The key idea is the **is a** relationship like a Car is a Vehicle.

What is the main benefit of using inheritance in object-oriented programming?

Learn how to build clean, secure, and scalable applications with Object-Oriented Programming in Python. Cover the fundamentals of classes and objects, then moves into advanced concepts such as inheritance, composition, polymorphism, and encapsulation. With clear explanations and practical examples, you'll develop the ability to design Python programs that are powerful, maintainable, and ready for real-world use.

Learn the core building blocks of object-oriented programming in Python. This section covers classes, objects, methods, and variables, giving you a solid base to understand how OOP organizes and structures code.

Explore how classes can share and extend functionality. You'll learn different inheritance patterns, from simple hierarchies to multiple inheritance and abstract classes, and see how they enable code reuse and scalability.

Discover how to build flexible systems by combining objects. Instead of relying only on inheritance, you'll see how composition lets you assemble behaviors in a modular, adaptable way.

Understand how different objects can share a common interface while behaving in their own way. This section shows how method overriding, interfaces, and protocols make your code more dynamic and reusable.

Learn how to safeguard internal data and control access to class attributes. You'll explore private attributes, getters and setters, and data-hiding techniques that keep your classes secure and maintainable.
