我可以在 python 中使用库抽象吗? [英] Can I use library abstractions in python?

问题描述

我正在使用:

for root, dirs, files in os.walk(rootDir):

浏览目录.都很酷.但是，我在 Windows 7 上运行，它当然具有库抽象.例如，图片库可能映射到 c:\users\me 和 c:\users\share有什么办法可以在 python 中使用这个库抽象吗?

to navigate around directories. All cool. However, I am running on windows 7 which of course has the library abstraction. So for example the picture library might map to c:\users\me and c:\users\share Is there any way I can use this library abstraction with python?

推荐答案

除非我对这个功能的工作方式有误解(我面前实际上没有一个 Win7 框)，否则你将不得不访问 WindowsShell API 以访问库.

Unless I'm wrong about how this feature works (I don't actually have a Win7 box in front of me), you will have to access the Windows Shell APIs in order to access libraries.

阅读 MSDN 杂志中的介绍库，看起来很漂亮很明显，只处理文件系统的应用程序会将库视为一个常规目录，甚至没有任何关于构成库的各种分散目录的指示.除非您总是坚持使用花哨的文件选择器对话框来获取所有路径(在这种情况下，用户会看到库，但最终总是选择一个特定的文件夹，因此您不必处理库)，您必须明确使用外壳 API.

Reading Introducing Libraries from MSDN Magazine, it seems pretty clear that apps that just deal with the filesystem will see a library as just a regular directory, and not even have any indication of the various scattered directories that make up the library. Unless you always stick to the fancy file-chooser dialogs to get all paths (in which case the user sees libraries, but always ends up picking a specific folder, so you don't have to deal with libraries), you have to explicitly use the shell APIs.

我认为您想从 Windows 库 用于开发指南和 IShellLibrary 供参考.

I think you want to start at Windows Libraries for the dev guide and IShellLibrary for the reference.

这些显然是 COM API，因此您可能想要使用 win32com 从 Python 访问它们.(您可以使用 ctypes 并处理 C 风格的 COM 内容，但您真的不想这样做.)可能有人已经将这些 COM 对象包装在一个漂亮的 Python 接口中——我在快速 PyPI 和 ActiveState 搜索中没有找到任何内容，但您可能想尝试更认真的搜索.

These are obviously COM APIs, so you probably want to use win32com to access them from Python. (You could use ctypes and deal with the COM stuff C-style, but you really don't want to.) It's possible that someone has already wrapped up these COM objects in a nice Python interface—I didn't find anything in quick PyPI and ActiveState searches, but you might want to try a more serious search.

当然，您也可以使用 IronPython 并使用 .NET API 而不是本机 API.

Alternatively, of course, you could use IronPython and use the .NET APIs instead of the native ones.
