How are classes created in Python?

class Animal:

    def __init__(self, name):

        self.name = name

    def speak(self):

        pass

class Dog(Animal):

    def speak(self):

        return f"{self.name} says Woof!"

class Cat(Animal):

    def speak(self):

        return f"{self.name} says Meow!"

dog = Dog("Buddy")

cat = Cat("Whiskers")

print(dog.speak())  # Output: Buddy says Woof!

print(cat.speak())  # Output: Whiskers says Meow!
