Tkinter 程序在 while 循环中没有响应

Question

我发现了一些关于这个主题的其他问题，但我一个都不明白。

我正在尝试制作一个每 x 分钟发送一条消息的程序，但由于循环中的 time.sleep 程序不再响应。 我尝试了多线程，但它似乎不起作用。我也找到了 root.after 但我认为我不能在 while 循环中使用它。

无论如何，这是我的代码：

对于这个问题，多线程似乎有点矫枉过正。你可以试试这样的。

import time
send_message()
last_message = time.time() 
while:
    do_stuff()
    if time.time()-last_message > 60*x:  # time.time() - last_message gives the difference in seconds between now and when the last message was send.
        send_new_message()
        last_message = time.time()
