Python を使用して、多重継承の一般的なパターンと実装例を示します。

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

    def eat(self):
        print(f"{self.name} is eating")

    def sleep(self):
        print(f"{self.name} is sleeping")


class Flyable:
    def fly(self):
        print(f"{self.name} is flying")


class Swimmable:
    def swim(self):
        print(f"{self.name} is swimming")


class Bird(Animal, Flyable):
    def __init__(self, name):
        super().__init__(name)

    def eat(self):
        super().eat()
        print("Bird is eating")

    def sleep(self):
        super().sleep()
        print("Bird is sleeping")


class Fish(Animal, Swimmable):
    def __init__(self, name):
        super().__init__(name)

    def eat(self):
        super().eat()
        print("Fish is eating")

    def sleep(self):
        super().sleep()
        print("Fish is sleeping")


class Duck(Bird):
    def __init__(self, name):
        super().__init__(name)


class Penguin(Bird, Swimmable):
    def __init__(self, name):
        super().__init__(name)
