# 反射:# hasattr() 判断一个对象里是否有对应的 name_str 字符串的方法# getattr() 根据字符串获得对象里的对应的方法的内存地址 后面+()可调用# setattr(obj, 'name', value) 通过字符串设置一个值# delattr(obj, "str")def eat(self): print("eat")class Dog(object): def __init__(self, name, age): self.name = name self.age = age def talk(self, who): print("%s is talking wangwangwnag with %s!"% (self.name, who))d = Dog("L", 11)action = input("action:>>").strip()if hasattr(d, action): func = getattr(d, action) func("Jy") print(d.name) delattr(d, 'name')else: setattr(d, action, eat) func = getattr(d, action) func(d)print(d.name)
