写一个八路抢答器的程序

抢答器程序：

import threading

class Buzz:
    def __init__(self, n):
        self.n = n
        self.count = 0
        self.lock = threading.Lock()
        self.cv = threading.Condition()

    def buzz(self):
        while True:
            with self.cv:
                self.cv.wait()
                print("Buzz")
                self.count += 1
                if self.count >= self.n:
                    self.cv.notify_all()
                    return

class Player:
    def __init__(self, name, buzz):
        self.name = name
        self.buzz = buzz

    def run(self):
        while True:
            ans = input(f"{self.name} buzzer: ")
            with self.buzz.lock:
                if self.buzz.count >= self.buzz.n:
                    return
                if ans == "buzz":
                    with self.buzz.cv:
                        self.buzz.cv.notify()
                        self.buzz.count += 1
                        if self.buzz.count >= self.buzz.n:
                            self.buzz.cv.notify_all()
                            return

if __name__ == "__main__":
    n = 3
    buzz = Buzz(n)
    buzz_thread = threading.Thread(target=buzz.buzz)
    buzz_thread.start()

    players = [
        Player("Alice", buzz),
        Player("Bob", buzz),
        Player("Charlie", buzz),
    ]
    player_threads = [threading.Thread(target=p.run) for p in players]
    for t in player_threads:
        t.start()
    for t in player_threads:
        t.join()
    buzz_thread.join()

    print("Game over")

程序实现了一个八路抢答器游戏，其中 Buzz 类负责判断何时有人抢答成功，Player 类负责处理每个玩家的抢答，主程序启动 Buzz 和若干个 Player 线程并等待它们结束。程序运行时，玩家在终端上输入 buzz 按钮即可进行抢答。当有一个玩家抢答成功后，程序输出 Buzz 并结束游戏
