In the world of object-oriented programming (OOP), inheritance and metaclasses are two powerful concepts that can take your Python skills to new heights. While inheritance allows you to create new classes based on existing ones, metaclasses give you the ability to customize the behavior of class creation itself.

In this article, we’ll dive into these concepts and explore their practical applications with up-to-date code examples.

Inheritance: Building Upon Existing Classes

Inheritance is a fundamental principle of OOP that enables code reuse and promotes modularity. By inheriting from an existing class, you can create a new class that inherits all the attributes and methods of the parent class. This allows you to build upon existing functionality and add or modify behavior as needed.

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

    def speak(self):
        print("The animal makes a sound.")

class Dog(Animal):
    def speak(self):
        print("The dog barks.")

my_dog = Dog("Buddy")
my_dog.speak()  # Output: The dog barks.
