我正在尝试编写一个程序,该程序列出一个文件夹中的所有 .xml 文件,然后将它们复制到另一个目录并从原始目录中删除。程序的这部分工作正常。我想这样做,以便我可以单击 GUI 中的按钮并让它扫描和处理文件夹,直到我按下按钮将其关闭。同样,打开它不是问题,但试图阻止它让我难过。我希望它在两者之间等待一段时间,但使用 time.sleep(x) 会冻结整个程序,并且在它停止睡眠之前不允许我输入任何命令,只是让它处理然后再次睡眠。关于如何从 GUI tkinter 按钮基本上启动/停止 while 循环的任何建议?
代码如下:

FileLock 功能可以在这里找到,如果您想知道它可以完美地工作,但我把它留了空间/可读性。我知道我的代码很草率,但我才刚刚开始编程。
非常欢迎任何建议/替代方法!
顺便说一句:exemel 是我要循环的函数!
