Summary  
This chapter covers how subclasses inherit attributes and methods from base classes in object-oriented programming, allowing shared behavior to be defined once in a parent class and extended or specialized in child classes.

General domain of usage  
object-oriented modeling of entities

Implementation of inheritance in Python is done through **base classes (parents)** and **subclasses (children)**.

A **base class** defines general properties and behaviors, while a **subclass** inherits these features and can extend them with its own.

This makes the base class the **foundation**, and the subclass the **specialized implementation** that adds flexibility.

What is the role of a subclass in Python inheritance?

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.
