帮我用Python写个猜拳程序

当然可以，以下是一个简单的猜拳程序的 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（1-3）："))
    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("输入错误，请重新输入！")

希望这个程序能够帮助你玩得开心！
