如何使用 Python 获取最前面的 Windows 资源管理器窗口的目录路径？

Question

我的问题是我正在制作一个程序，该程序将根据用户作为文件资源管理器打开的文件夹获取文件数据......我已经浏览了整个互联网以找到答案，但似乎这个问题从来没有人面对过。许多答案与项目文件所在的当前工作目录有关。

所以，我基本上想要用户当前在文件资源管理器中查看的文件夹的路径...

嗯，我的解决方案相当复杂，但我已经为你找到了这个。希望对您有所帮助。

我能想到的最好方法是编写 Python 软件以在资源管理器中使用上下文菜单。通过快速谷歌搜索，我找到了一个有趣的库：https://pypi.org/project/context-menu/

我想没有明智的方法可以从另一个进程中读取数据。这会导致安全问题。
