Python写的计时软件求助
本帖最后由 MrrrrrrrDou 于 2024-4-20 12:40 编辑这是我写的一个计时的软件，但是目前有两个问题，
①我已经在 后面的def on_double_click(self, event):中写了当我双击时首先停止之前的计时 # 停止该行已有的倒计时
self.stop_countdown(selected_item)，但是实际运行起来并不会，他会和前面的数据打架，什么原因呀？
②如果我关闭程序，他就不会计时了，我希望每次打开他能够判断我现在的时间和刷新时间的差值，然后倒计时，怎么做
下面是完整代码

root.mainloop() 关于停止之前的计时：你已经在 on_double_click 方法中尝试停止之前的计时，但出现问题的地方是在于如何识别和停止正确的计时线程。在 stop_countdown 方法中，你可以尝试根据选中的怪物名称来查找对应的计时线程，并停止它。
关于每次打开程序都计时：你可以在程序启动时，检查每个怪物的击杀时间和刷新时间，计算出剩余时间，然后启动一个新的倒计时线程。这样，即使关闭程序再打开，仍能保持计时状态。

你这是ai回复的吧，我自己问过AI好多遍了，解决不了才过来求助的 确实会，等待大佬修复代码
你试试能不能创建一个多线程，等待用户按键然后再杀进程，没写过python思路应该通用 回答第一个问题。

经过调试，发现每次双击时，这个字典 `self.active_countdown_threads` 永远是空的，正确情况下该字典应该包含上一次双击时所创建的 Thread 对象。
所以调用 `self.stop_countdown()` 时根本没有正确终止线程，因为上一次双击时所创建的 Thread 对象已经被删除了。
具体情况如下：
解决方法粗暴点，修改 `update_countdown` 的代码，直接休息 1s。
```python
if remaining_time > 0:
# 递归调用 update_countdown 函数，间隔 1000 毫秒（1秒）
time.sleep(1)
return update_countdown(remaining_time - 1)
# self.master.after(1000, update_countdown, remaining_time - 1)
else:
# 倒计时结束后，移除该行的倒计时线程
del self.active_countdown_threads
```
另外，取消线程不要使用 `.join()`，实际上它是在等待线程执行完，而不是立即结束。可以利用线程通信，让另一个线程自动结束。 FitContent 发表于 2024-4-20 17:52
回答第一个问题。
这样改完后，我的倒计时不会动了{:1_885:} 简单弄了一下第一个问题，第二个问题没看懂

简单弄了一下第一个问题，第二个问题没看懂
# 导入所需的库
import tkinter as ...
# 倒计时结束后，移除该行的倒计时线程
del self.active_countdown_threads
这个代码有问题，不能直接删除，会导致每次拿到active_countdown_threads都是空的 Loker 发表于 2024-4-20 18:23
# 倒计时结束后，移除该行的倒计时线程
del self.active_countdown_threads
第二个问题简单来说就是，我关掉软件时，我希望倒计时还在进行（事实上不是），当我再次打开软件，我希望倒计时是正确的而且正在运行
