OOP Python 4- Understanding Abstraction in Python

Abstraction, a foundational concept in Python, allows developers to create a superclass that carries common features and functions of subclasses without having an object of its own.

Key Concepts:

• Common Features: Abstraction enables the creation of a superclass that encapsulates shared attributes and methods of subclasses.
• Template Definition: Methods in the abstract class can serve as templates to be overridden by subclasses.

Benefits of Abstraction:

• Simplified Design: Abstract classes provide a blueprint for subclasses, simplifying the overall design.
• Modularity: Encapsulation of common features enhances code modularity and maintainability.

Example: Animal Hierarchy Consider an abstract class "Animal" with an abstract method "make_sound." Subclasses like "Dog" and "Cat" will implement this method according to their specific sound.

from abc import ABC, abstractmethod

class Animal(ABC):
    @abstractmethod
    def make_sound(self):
        pass  # Abstract method to be implemented by subclasses

class Dog(Animal):
    def make_sound(self):
        return "Woof!"

class Cat(Animal):
    def make_sound(self):
        return "Meow!"

# Usage
dog_instance = Dog()
cat_instance = Cat()

print(dog_instance.make_sound())  # Output: Woof!
print(cat_instance.make_sound())  # Output: Meow!

In this example, abstraction allows the "Animal" superclass to define a common method, "make_sound," which is implemented differently by its subclasses (Dog and Cat). This promotes a clean and modular design in Python.
