用python写一个猜拳游戏代码

好的，我可以回答这个问题。以下是一个简单的猜拳游戏的Python代码：

import random

print("欢迎来到猜拳游戏！")
print("请出拳：1.石头 2.剪刀 3.布")

while True:
    player = int(input("请输入你的选择（1/2/3）："))
    computer = random.randint(1, 3)

    if player == 1:
        if computer == 1:
            print("平局！")
        elif computer == 2:
            print("你赢了！")
        else:
            print("你输了！")
    elif player == 2:
        if computer == 1:
            print("你输了！")
        elif computer == 2:
            print("平局！")
        else:
            print("你赢了！")
    elif player == 3:
        if computer == 1:
            print("你赢了！")
        elif computer == 2:
            print("你输了！")
        else:
            print("平局！")
    else:
        print("请输入有效的选择！")

    play_again = input("是否再来一局？（y/n）")
    if play_again.lower() != "y":
        break

print("游戏结束，谢谢参与！")

希望这个代码能够帮到你！
