python编写猜拳程序

好的，以下是一个简单的 Python 猜拳游戏程序：

import random

print("欢迎来到猜拳游戏！")

while True:
    player = input("请出拳（1-石头，2-剪刀，3-布）：")
    while player not in ["1", "2", "3"]:
        player = input("输入有误，请重新出拳（1-石头，2-剪刀，3-布）：")

    player = int(player)
    computer = random.randint(1, 3)

    print("你出了%s，电脑出了%s。" % (player, computer))

    if player == computer:
        print("平局！")
    elif (player == 1 and computer == 2) or \
         (player == 2 and computer == 3) or \
         (player == 3 and computer == 1):
        print("恭喜你，你赢了！")
    else:
        print("很遗憾，你输了。")

    play_again = input("再玩一局？（是/否）：")
    play_again = play_again.lower()
    while play_again not in ["是", "否"]:
        play_again = input("输入有误，请重新输入（是/否）：")
        play_again = play_again.lower()

    if play_again == "否":
        break

print("游戏结束，谢谢参与！")

程序会不断循环，直到玩家选择退出游戏。玩家和电脑各出一种手势，程序会判断胜负并输出结果。玩家可以选择再玩一局或退出游戏。
