Class Inheritance

Code

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

class Dog(Animal):
    def speak(self):
        return f"{self.name}: Woof"

class Cat(Animal):
    def speak(self):
        return f"{self.name}: Meow"

def make_sound(animal):
    print(animal.speak())

make_sound(Dog("Buddy"))
make_sound(Cat("Kitty"))

Explanation

Subclasses inherit from parent classes and override methods, demonstrating polymorphism.
