os.listdir() always returns a list of all files in a directory. If you want
just the directories, you have to filter them out yourself:
>>> from os.path import join, isdir
>>> files = os.listdir('mydir')
>>> dirs = [f for f in files if isdir(join('mydir', f))]
Have you looked at the popular 'path' module
(http://www.jorendorff.com/articles/python/path/)? It eases common tasks when
handling filesystems very nicely.
