dir同样可以查找实例的属性字典

print(dir(p1))

下面是增删改查举例:

class Chinese:
    country='中国'
    def __init__(self,name):
        self.name=name
    def play_ball(self,ball):
        print('%s正在打%s' %(self.name))
print(Chinese.country)   '查看’

Chinese.country='Russian'   '修改'

Chinese.fuse='黄色'  '增加'

del Chinese.fuse  '删除‘

def eat_food(self,food):
    pass
Chinese.food=eat_food   '增加函数属性’

def test(self):
    pass
Chinese.play_ball=test   '修改函数属性'
