6编写一个程序，模拟石头、剪刀、布的游戏，并决定谁是赢家。

为了编写一个简单的石头、剪刀、布游戏，我们可以创建一个交互式的命令行程序。以下是使用Python的一个简单实现：

import random

def game():
    choices = ["石头", "剪刀", "布"]
    player_choice = input("玩家，请出拳（石头、剪刀、布）: ").lower()
    computer_choice = random.choice(choices)

    print(f"电脑出了 {computer_choice}.")

    if player_choice == computer_choice:
        result = "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"):
        result = "玩家赢了!"
    else:
        result = "电脑赢了!"

    print(result)

if __name__ == "__main__":
    game()
