python - 我如何添加一个倒计时的计时器，当它用完时它会重新启动我的程序

问题描述

我是一个非常新的初学者编码器，我还不太了解。我正在尝试创建一个猜谜游戏，并且想在程序中添加一个计时器。计时器的工作方式是我设置了一个固定的时间，即 60 秒，一旦时间用完，程序就会停止，基本上就像“对不起，你没时间了。你想再试一次吗？ "

我已经在 YouTube 和 Stackoverflow 上搜索了一些视频，但我要么不明白，要么无法做到。

我已经看了 4 次这个视频，但仍然不知道该怎么做。因此，如果有人愿意向我解释/告诉我如何增加时间，那将不胜感激

def main():
    import random
    n = random.randint(1, 99)
    chances = 5
    guess = int(input("Player 2 please enter an integer from 1 to 99, you have 5 chances: " ))
    while n != "guess":
        chances -=1
        if chances ==0:
            print("out of chances, it is now player 2's turn to play. The number was", n)
            break
        if guess < n:
            print("guess is low you have",chances,"chances left")
            guess = int(input("Enter an integer from 1 to 99: "))
        elif guess > n:
            print ("guess is high you have",chances, "chances left")
            guess = int(input("Enter an integer from 1 to 99: "))
        else:
            print("you guessed it and have", chances, "chances left")
            break
            
        import random
    n1 = random.randint(1, 99)
    chances1 = 0
    guess1 = int(input("Player 2 please enter an integer from 1 to 99, you have 5 chances: "))
    while n1 != "guess":
        chances1 +=1
        if chances1 ==5:
            print("out of chances, the number was", n1)
            break
        if guess1 < n1:
            print("guess is low you have",chances1,"chances left")
            guess1 = int(input("Enter an integer from 1 to 99: "))
        elif guess > n1:
            print ("guess is high you have",chances1, "chances left")
            guess1 = int(input("Enter an integer from 1 to 99: "))
        else:
            print("you guessed it and have", chances1, "chances left")
            break
    retry=input("would you like to play again? (please choose either 'yes' or 'no' )")
    if retry == "yes":
        main()
    elif retry == "no":
        print("Okay. have a nice day! :D ")
    else:
        print("Invalid input")
main()

这是我的代码。对于任何反馈，我们都表示感谢。

解决方案

要解决您的问题，您必须使用Thread. 我拿了你的代码我在开始时添加了线程，试着看看。

线程是可以run在主程序旁边执行函数（其函数）的对象。这就是所谓的并行编程。
在这里你需要它，因为你想：

  1. 检查播放器的输入
  2. 倒数

我不会更正您的代码或重写它，我只是添加了线程并使其工作。这很容易：

  1. 我要求sleep给定的时间 ( _TIME_LIMIT]
  2. 计时器结束时发出一点声音。
  3. 我将变量设置为True，这意味着计时器结束

通过一些重写，您将能够在 Thread 更改变量时中断主循环。但这超出了最初问题的范围，请随时改进您的游戏。
目前，您需要输入一个数字才能知道时间是否结束。这就是我添加小噪音的原因（如果没有，您将没有任何提示）。

请随时提出任何问题。
希望这会帮助你。
