首先，我做了一个脚本来过滤特定文件夹中的文件，然后将所选文件复制并粘贴到另一个文件夹中，
现在我在实现UI Tkinter时遇到问题，当原始文件夹路径和文件类型选择来自界面时，我找不到一种可行的方法。
如果有人告诉我怎么做，我将不胜感激。

我已经根据您的代码创建了一个有效的版本。我已经在代码中添加了注释作为描述。可能是这种方式，因为您的代码很长，而且问题出在不同的地方，所以更改更容易理解。

测试和输出：
test1文件夹包含一个jpeg文件。
>>> ll test1/
total 8
drwxrwxr-x 2 user user 4096 Jul 3 13:19 ./
drwxrwxr-x 18 user user 4096 Jul 3 13:32 ../
-rw-rw-r-- 1 user user 0 Jul 3 13:19 test.jpeg
test2文件夹为空。该文件夹是目的地。
>>> ll test2/
total 8
drwxrwxr-x 2 user user 4096 Jul 3 13:32 ./
drwxrwxr-x 18 user user 4096 Jul 3 13:32 ../
运行代码（选择test1文件夹和a过滤器）：
>>> python3 test.py
/home/user/test1
Path: /home/user/test1
Filter: a
a) Filter Images
b) Filter Videos
c) Filter Audio
d) Filter Documents
e) Filter Others
test.jpeg
Copied file: /home/user/test1/test.jpeg
检查test2文件夹：
>>> ll test2/
total 8
drwxrwxr-x 2 user user 4096 Jul 3 13:37 ./
drwxrwxr-x 18 user user 4096 Jul 3 13:37 ../
-rw-rw-r-- 1 user user 0 Jul 3 13:37 test.jpeg
如您在上方看到的，脚本按预期工作。
