python几个小程序

import randomwhile True:    player = input("输入：|剪刀（0）| 石头（1）| 布（2）| 退出(q)|：\n")    if(player == "q" or player == "0" or player == "1" or player == "2"):          if player == "q":            print("欢迎再来\n")            break        else:            player = int(player)            computer = random.randint(0,2)            if (computer > player):                print("你输了！再来！\n")            elif (computer == player):                print("平局\n")            else:                print("你赢了！\n")    else:        print("输入错误!重新输入\n")        continue
