静态方法：只是名义上归类管理，实际上在静态方法里不能访问类或实例中的任何属性

class Dog(object):    def __init__(self,name):        self.name=name    @staticmethod    def eat(self,food):        print('%s is eating %s'%(self.name,food))d=Dog('wangcai')d.eat(d,'骨头')>>>wangcai is eating 骨头

 

class Dog(object):    def __init__(self,name):        self.name=name    @staticmethod    def eat(name1,food):        print('%s is eating %s'%(name1,food))d=Dog('wangcai')d.eat('旺财','骨头')>>>旺财 is eating 骨头
