Describe how you apply the principles of object-oriented programming in your projects

When developing projects in Python, I apply the main principles of object-oriented programming (OOP):

• Encapsulation: I hide the internal implementation details of classes, providing only the necessary methods for interaction. This helps protect data and simplifies maintenance.

• Inheritance: I create base classes with common functionality and extend them in derived classes to avoid code duplication and increase reusability.

• Polymorphism: I use the same interfaces or methods across different classes, which allows writing more flexible and extensible code.

• Abstraction: I identify key entities and their behaviors to focus on what's important and simplify the architecture.

Example:

class Animal:
    def speak(self):
        raise NotImplementedError("Subclasses must implement this method")

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

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

animals = [Dog(), Cat()]
for animal in animals:
    print(animal.speak())

This approach helps create clean, understandable, and easily maintainable code.
