# 多重继承 继承了Mammal, Runnable等
class Dog(Mammal, Runnable):
pass
class Bat(Mammal, Flyable):
# 蝙蝠
pass
class Parrot(Bird, Flyable):
# 鹦鹉
pass
class Ostrich(Bird, Runnable):
# 鸵鸟
pass
dog = Dog()
# 非蛋生。。。。。
dog.run()
# Running...
bat = Bat()
# 非蛋生。。。。。
bat.fly()
# Flying...
# MixIn混合继承（一般简单业务都是单一主线继承）
# 为了更好地看出继承关系，我们把Runnable和Flyable改为RunnableMixIn和FlyableMixIn
