Object-Oriented Programming (OOP) is a fundamental concept in Python, and understanding inheritance and instance attributes is crucial for writing efficient and maintainable code.

In this article, we’ll dive into these concepts with clear explanations and up-to-date code examples, ensuring you can apply them confidently in your projects.

Inheritance: Reusing and Extending Code

Inheritance is a mechanism that allows you to create a new class (child class) based on an existing class (parent class). The child class inherits all the attributes and methods from the parent class, enabling code reuse and promoting modularity. Here’s a simple example:

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

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

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

    def make_sound(self):
        print("Woof!")

dog = Dog("Buddy", "Labrador")
dog.make_sound()  # Output: Woof!
