#经典类  （python3中也是新式类）
class chinese:
    "这是一个类"
    pass

# print(chinese)
# p1=chinese()#实例化
# print(p1)

#新式类要加object
class chinese(object):
    pass



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