What knowledge and experience with object-oriented programming in Python can you demonstrate?

Object-oriented programming (OOP) in Python is implemented through classes and objects. I can create classes with attributes and methods, use inheritance to extend functionality, apply encapsulation through private and protected attributes, and also use polymorphism to override methods.

Example of a class with inheritance and method overriding:

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

    def speak(self):
        return "..."

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

dog = Dog("Sharik")
print(dog.name)  # Sharik
print(dog.speak())  # Woof!

I am also familiar with concepts such as abstract classes (via the abc module), properties for managing access to attributes, and I understand how to use composition and aggregation to build complex objects.
