python编制剪刀石头布三局两胜

Python编写剪刀、石头、布游戏的三局两胜规则通常会涉及用户输入选择和随机计算机选择，以及游戏结果判断。以下是一个简单的示例：

import random

def game():
    choices = ['rock', 'paper', 'scissors']
    
    def user_choice():
        while True:
            user_input = input("请输入(rock/paper/scissors)，或者输入'quit'退出游戏：")
            if user_input.lower() == 'quit':
                return None
            elif user_input.lower() in choices:
                return user_input.lower()
            else:
                print("无效的选择，请重新输入。")

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

    for i in range(2):
        user_score = 0
        computer_score = 0
        
        print(f"比赛开始! ({i+1}/{3})")
        for _ in range(3):
            user_play = user_choice()
            if user_play is None:
                break
            
            computer_play = computer_choice()
            result = {
                ('rock', 'scissors'): '用户赢',
                ('scissors', 'paper'): '用户赢',
                ('paper', 'rock'): '用户赢',
                ('rock', 'rock'): '平局',
                ('scissors', 'scissors'): '平局',
                ('paper', 'paper'): '平局'
            }.get((user_play, computer_play), '电脑赢')
            
            print(f"{user_play} 对 {computer_play}: {result}")
            if result.startswith('用户'):
                user_score += 1
            else:
                computer_score += 1
            
        if user_score > computer_score:
            print(f"恭喜您赢得了{user_score}/{3}场比赛，您获胜了!")
        elif user_score < computer_score:
            print(f"很遗憾，您输了{user_score}/{3}场比赛，电脑获胜了!")
        else:
            print("双方打成了平局!")

game()
