要格式化的是字符串，所以把 %d 改成 %s

class Game:
    topscore = 0
    def __init__(self,playername):
        self.playername = playername
    @staticmethod
    def help():
        print("帮助信息：让僵尸进门。")
    @classmethod
    def showtopscore(cls):
        print("历史记录%d"%cls.topscore)

    def start_game(self):
        print("%s开始游戏了！"%self.playername)
Game.help()
Game.showtopscore()
game = Game("小明")
game.start_game()
