Object-Oriented Programming (OOP) is a fundamental concept in software development, and Python provides excellent support for it. In this article, we’ll explore two essential aspects of OOP in Python: inheritance and design patterns.

We’ll dive into practical examples and code snippets to help you understand these concepts and apply them effectively in your projects.

Inheritance: Building on Existing Code

Inheritance is a mechanism that allows a new class to be based on an existing class, inheriting its attributes and methods. This promotes code reuse and helps in creating a hierarchical structure of classes. In Python, inheritance is achieved using the following syntax:

class DerivedClass(BaseClass):
    # class definition

Here’s an example:

class Animal:
    def __init__(self, name):
        self.name = name

    def speak(self):
        print("The animal speaks")

class Dog(Animal):
    def __init__(self, name, breed):
        super().__init__(name)
        self.breed = breed

    def speak(self):
        print("The dog barks")…
