python猜拳三局两胜

### Python 实现三局两胜的石头剪刀布游戏

为了创建一个三局两胜的游戏模式，程序需要跟踪每一轮的结果直到一方赢得两次。下面是一个完整的Python代码示例：

import random

def get_user_selection():
    choices = ['石头', '剪刀', '布']
    selection = input("请输入您的选择 (石头, 剪刀, 或者 布): ")
    while selection not in choices:
        print('无效的选择')
        selection = input("请重新输入 (石头, 剪刀, 或者 布): ")
    return selection

def get_computer_selection():
    selections = ['石头', '剪刀', '布']
    return random.choice(selections)

def determine_winner(user_choice, computer_choice):
    if user_choice == computer_choice:
        return "平局"
    
    win_conditions = {
        "石头": "剪刀",
        "剪刀": "布",
        "布": "石头"
    }
    
    if win_conditions[user_choice] == computer_choice:
        return "用户赢"
    else:
        return "计算机赢"

def play_round():
    user_score = 0
    computer_score = 0
    
    while max(user_score, computer_score) < 2 and abs(computer_score - user_score) != 1:
        user_selection = get_user_selection()
        computer_selection = get_computer_selection()

        print(f'您选择了 {user_selection}, 计算机选择了 {computer_selection}')
        
        result = determine_winner(user_selection, computer_selection)
        print(result)
        
        if result == "用户赢":
            user_score += 1
        elif result == "计算机赢":
            computer_score += 1
        
        print(f'当前比分: 用户 {user_score} : {computer_score} 计算机\n')

    final_result = "用户胜利" if user_score > computer_score else "计算机胜利"
    print(final_result)

if __name__ == "__main__":
    play_round()

在这个版本中，`play_round()` 函数负责管理整个游戏流程，确保只有当某一方获得两个胜利或者另一方落后超过一分时才会停止[^4]。
