用Python写一段猜拳代码

### 回答1：
好的，这是一段简单的猜拳代码：

import random

print("石头剪刀布游戏！")

while True:
    print("请出拳：1. 石头 2. 剪刀 3. 布")
    player = int(input("请输入："))
    
    while player not in [1, 2, 3]:
        player = int(input("无效输入，请重新出拳：1. 石头 2. 剪刀 3. 布"))
    
    computer = random.randint(1, 3)
    
    if player == 1 and computer == 2:
        print("你出了石头，电脑出了剪刀，你赢了！")
    elif player == 2 and computer == 3:
        print("你出了剪刀，电脑出了布，你赢了！")
    elif player == 3 and computer == 1:
        print("你出了布，电脑出了石头，你赢了！")
    elif player == computer:
        print("平局！")
    else:
        print("你输了！")
        
    response = input("是否再玩一局？(Y/N)")
    if response in ['N', 'n']:
        break

这段代码使用了`random`模块，用于生成电脑出拳的随机数。通过循环语句和条件判断语句，实现了猜拳的功能。

猜拳是一种非常经典的游戏，通过手势的选择，玩家可以决定胜负。下面是一个使用Python编写的简单猜拳代码：

import random

def get_computer_choice():
    """随机生成电脑的手势选择"""
    choices = ['剪刀', '石头', '布']
    computer_choice = random.choice(choices)
    return computer_choice

def determine_winner(player_choice, computer_choice):
    """判断胜负并输出结果"""
    result = ''

    if player_choice == computer_choice:
        result = "平局"
    elif (player_choice == '剪刀' and computer_choice == '布') or (player_choice == '石头' and computer_choice == '剪刀') or (player_choice == '布' and computer_choice == '石头'):
        result = "你赢了!"
    else:
        result = "你输了!"

    print("电脑选择了: {}".format(computer_choice))
    print(result)

def play_game():
    """开始游戏"""
    choices = ['剪刀', '石头', '布']
    print("欢迎来到猜拳游戏!")
    print("请根据以下选项选择：")
    for index, choice in enumerate(choices):
        print("{}: {}".format(index+1, choice))
    player_choice = int(input("请选择(输入对应数字): "))
    player_choice = choices[player_choice - 1]
    computer_choice = get_computer_choice()
    determine_winner(player_choice, computer_choice)

play_game()

以上是一个简单的猜拳游戏代码，通过在控制台上输入数字选择手势，然后与电脑的随机选择进行对比，判断胜负，并打印出结果。

下面是一个使用Python编写的简单猜拳游戏代码：

import random

def main():
    choices = ['石头', '剪刀', '布']
    
    while True:
        player_choice = input("请选择（石头/剪刀/布）：")
        computer_choice = random.choice(choices)
        
        print(f"你选择了：{player_choice}")
        print(f"电脑选择了：{computer_choice}")
        
        result = determine_winner(player_choice, computer_choice)
        print(result)
        
        play_again = input("再玩一次？（是/否）")
        if play_again.lower() != "是":
            break

def determine_winner(player_choice, computer_choice):
    if player_choice == computer_choice:
        return "平局"
    elif (player_choice == '石头' and computer_choice == '剪刀') or \
         (player_choice == '剪刀' and computer_choice == '布') or \
         (player_choice == '布' and computer_choice == '石头'):
         return "你赢了！"
    else:
        return "你输了！"

if __name__ == '__main__':
    main()

这段代码首先定义了三个选择（石头、剪刀、布），然后使用一个循环来让玩家重复进行游戏。每次循环，玩家会被要求选择一个选项，然后电脑会随机选择一个选项。接着，根据玩家和电脑的选择，使用`determine_winner`函数来判断胜负，并输出结果。最后，玩家可以选择是否再次进行游戏。
