【面向对象】静态方法

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
