python静态属性

@property 类属性不能传参数，但可以使用 self，根据其只能使用self属性，所以利用@setter赋值

class Dog(object):
 
    def __init__(self,name):
        self.name = name
        self.__food =None
    @property
    def eat(self):
        print("%s is eating %s "%(self.name,self.__food))
    @eat.setter
    def eat(self,food):
        self.__food=food
        print("set to food",food)
 
 
d = Dog("hh")
d.eat
d.eat = 'baozi'
d.eat
