python人机猜拳三局两胜

Python人机猜拳是一种简单的游戏，玩家与计算机进行三局两胜的对决。游戏规则如下：
1. 玩家和计算机同时出拳，可以选择石头、剪刀或者布。
2. 石头胜剪刀，剪刀胜布，布胜石头。
3. 如果双方出拳相同，则为平局。
4. 先达到两局胜利的一方获得最终胜利。

以下是Python实现人机猜拳游戏的示例代码：

import random

def get_player_choice():
    choice = input("请输入你的选择（石头/剪刀/布）：")
    while choice not in ["石头", "剪刀", "布"]:
        choice = input("输入无效，请重新输入你的选择（石头/剪刀/布）：")
    return choice

def get_computer_choice():
    choices = ["石头", "剪刀", "布"]
    return random.choice(choices)

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 "玩家胜利"
    else:
        return "计算机胜利"

def play_game():
    player_score = 0
    computer_score = 0

    while player_score < 2 and computer_score < 2:
        player_choice = get_player_choice()
        computer_choice = get_computer_choice()

        print("玩家选择：", player_choice)
        print("计算机选择：", computer_choice)

        winner = determine_winner(player_choice, computer_choice)
        print("本局结果：", winner)

        if winner == "玩家胜利":
            player_score += 1
        elif winner == "计算机胜利":
            computer_score += 1

    if player_score > computer_score:
        print("恭喜，玩家获得最终胜利！")
    else:
        print("很遗憾，计算机获得最终胜利！")

play_game()
