Animal是父类，Dog和Cat继承父类，然后创建一个工厂类，通过静态方法来设置匹配规则， 同样的示例化方式和调用方式，根据传入的内容的不同，结果也不一样。
class Animal: def __init__(self, name): self.__name = name def getName(self): return self.__name class Dog(Animal): def __init__(self, name): super().__init__(name) def getName(self): return "dog" class Cat(Animal): def __init__(self, name): super().__init__(name) def getName(self): return "cat" class AnimailMake: @staticmethod def makeanimial(name): am = None if name == "cat": am = Cat(name) elif name == "dog": am = Dog(name) else: am = Animal(name) return am if __name__ == '__main__': am = AnimailMake.makeanimial("cat") print(am.getName()) am = AnimailMake.makeanimial("dog") print(am.getName()) am = AnimailMake.makeanimial("?") print(am.getName())转载于:https://www.cnblogs.com/c-x-a/p/10950863.html
