如何在PYTHON里面实现多态

1、首先这里新建一个PY文档。

3、class Children(object): def __init__(self, name): self.name = name def play(self): print("playing video games.") class Baby(Children): def play(self): print("playing toys.") class Adult(object): def __init__(self): self.name = name def play_with_kid(self, kid): print("%s and %s are %s" %(kid.name, self.name, kid.play)) #如果我们定义另外一个类，要求和另外两个父子类有关联，可以实现吗？

5、class Children(object): def __init__(self, name): self.name = name def play(self): print("playing video games.") class Baby(Children): def play(self): print("playing toys.") class Adult(object): def __init__(self, name): self.name = name def play_with_kid(self, kid): return "I am " + str(kid.play()) alice = Baby("Alice")father = Adult("Father")father.play_with_kid(alice)#但是这里要注意的是如果这样调用方法是不行的，因为属于None。
