Why doesn't this work as expected?

[David LeBlanc]

I'm trying to build a directory walker, doing some work on each actual 
file found in each directory. However, when I run the below code snippet 
on a directory containing both sub-directories and files, it says that 
all are not dirs.

What is not right?

TIA,

Dave LeBlanc

import sys
import os
import dircache
import re


def getDirs():
	print dircache.listdir("l:/languages/python")

	for dir in dircache.listdir("l:/languages/C"):
		if os.path.isdir(dir):
			print dir, "is a dir"
		else:
			print dir, "is not a dir"

getDirs()
