要格式化的是字符串，所以把 %d 改成 %s

1. class Game:
   
2.     topscore = 0
   
3.     def __init__(self,playername):
   
4.         self.playername = playername
   
5.     @staticmethod
   
6.     def help():
   
7.         print("帮助信息：让僵尸进门。")
   
8.     @classmethod
   
9.     def showtopscore(cls):
   
10.         print("历史记录%d"%cls.topscore)
    
11. 
    
12.     def start_game(self):
    
13.         print("%s开始游戏了！"%self.playername)
    
14. Game.help()
    
15. Game.showtopscore()
    
16. game = Game("小明")
    
17. game.start_game()
