It's no longer supported, but the 3rd party 'path' module used to be
the go-to module for this:
>>> from path import path
C:\Python26\lib\site-packages\path.py:32: DeprecationWarning: the md5
module is deprecated; use hashlib instead
import sys, warnings, os, fnmatch, glob, shutil, codecs, md5
>>> c = path('C:\\')
[path(u'C:\\AUTOEXEC.BAT'), path(u'C:\\boot.ini'), ...]
>>> (c + 'python26').listdir()
>>> (c / 'python26').listdir()
I've hand edited the results for brevity...
The module could do with some TLC to bring it up to date, but warning
aside it still seems to work fine under 2.6.
(From memory, I think the original author gave up when it became clear
it would never be integrated into the standard lib, which is a
shame, I think there's scope for a pathtools addition to the lib that
provides this level of convenience...)
There was also a PEP with another possible implementation:
Hope this helps.
