As contributor of the day, Jason Scheirer, pointed out, python has a simple, direct way to browse through the subdirectories of a directory–os.walk

Here is a bare-bones example of using it to print out the subdirectories in a path. The files variable of the 3-tuple is a list of files similar to the dirs variable that I loop through.

Thanks Jason for pointing out something I missed.

import os

theDir = 'c:/temp/'

for root, dirs, files in os.walk(theDir,True,None):
    for idir in dirs:
        print "     directory:   {0}/{1}".format(root,idir)
