请在上述代码增加统计并显示胜局，败局，平局的局数

为了增加对胜局、败局和平局的统计，你可以添加三个变量来跟踪这些结果，并在每次游戏结束后更新它们。这里是修改后的代码：

import random

# 初始化计数器
wins = 0
losses = 0
ties = 0

def get_player_choice():
    while True:
        choice = input("请输入你的选择 (S for 石头, J for 剪刀, B for 布, Q for 退出): ").lower()
        if choice in ['s', 'j', 'b', 'q']:
            return choice
        else:
            print("无效的选择，请输入S, J, B或Q。")

def get_computer_choice():
    choices = ['s', 'j', 'b']
    return random.choice(choices)

def play_game():
    global wins, losses, ties

    player = get_player_choice()
    computer = get_computer_choice()

    if player == 'q':
        print("游戏结束，感谢参与!")
        return

    print(f"你出了{player}, 对手出了{computer}.")

    if player == computer:
        result = "平局"
        ties += 1
    elif (player == 's' and computer == 'j') or \
         (player == 'j' and computer == 'b') or \
         (player == 'b' and computer == 's'):
        result = "你赢了!"
        wins += 1
    else:
        result = "你输了!"
        losses += 1

    print(f"{result}! 当前记录: 赢{wins}次, 跳{losses}次, 平{ties}局")

play_game()

现在当你玩完一局游戏后，程序会显示胜局、败局和平局的具体数目。如果你想知道更多关于如何进一步扩展或优化这个统计功能的问题，可以继续提问：
