List directories with a specified depth in Python

Question

I\'m want a function to return a list with directories with a specified path and a fixed depth and soon realized there a few alternatives. I\'m using os.walk quite a lot but

I really like phihag's answer. I adapted it to suit my needs.

import fnmatch,glob
def fileNamesRetrieve( top, maxDepth, fnMask  ):
    someFiles = []
    for d in range( 1, maxDepth+1 ):
        maxGlob = "/".join( "*" * d )
        topGlob = os.path.join( top, maxGlob )
        allFiles = glob.glob( topGlob )
        someFiles.extend( [ f for f in allFiles if fnmatch.fnmatch( os.path.basename( f ), fnMask ) ] )
    return someFiles

I guess I could also make it a generator with something like this:

def fileNamesRetrieve( top, maxDepth, fnMask  ):
    for d in range( 1, maxDepth+1 ):
        maxGlob = "/".join( "*" * d )
        topGlob = os.path.join( top, maxGlob )
        allFiles = glob.glob( topGlob )
        if fnmatch.fnmatch( os.path.basename( f ), fnMask ):
            yield f

Critique welcome.
