dynamic inheritance

A true classic when it comes to OOP patterns; refer to your text book.

import random


class Cat:
    def speak(self):
        print('Meow!')


class Dog:
    def speak(self):
        print('Woof!')


class RandomAnimal(random.choice((Cat, Dog))):
    pass


if __name__ == '__main__':
    RandomAnimal().speak()

Woof!
