比大小游戏：石头剪刀布python

"比大小游戏"，比如经典的“石头、剪刀、布”（Rock-Paper-Scissors），是一个简单的命令行交互式游戏，通常使用Python编写。在游戏中，用户和计算机随机选择手势，然后根据规则判断胜负：石头砸剪刀，剪刀剪布，布包石头。下面是一个基础版本的Python实现：

import random

# 定义手势列表
gestures = ["石头", "剪刀", "布"]

def player_choice():
    while True:
        user_input = input("请输入你的选择（石头、剪刀、布）：")
        if user_input.lower() in gestures:
            return user_input
        else:
            print("无效的选择，请重新输入。")

def computer_choice():
    return random.choice(gestures)

def compare_choices(player, computer):
    if player == computer:
        return "平局"
    elif (player == "石头" and computer == "剪刀") or \
         (player == "剪刀" and computer == "布") or \
         (player == "布" and computer == "石头"):
        return "你赢了!"
    else:
        return "电脑赢了!"

def play_game():
    player = player_choice()
    computer = computer_choice()
    result = compare_choices(player, computer)
    print(f"{player} 对 {computer}, 结果是 {result}")

play_game()
