如何在 Windows 上使用 Python 更改文件夹图标? [英] How to change folder icons with Python on windows?

问题描述

我想编写一个实用程序脚本来更改具有特定名称的文件夹的图标.这在 python 中可行吗?如果没有，有没有其他方法可以做到这一点?

I would like to write a utility script that changes the icon of folders with a specific name. Is this possible in python? If not, is there any other way of doing this?

谢谢
