Python os.walk example

This is my OLD blog. I've copied this post over to my NEW blog at:

Here is a simple os.walk() example which walks your directory tree and returns the path, a list of directories, and a list of files:

import os

path = "c:\\python25"

i = 0
for (path, dirs, files) in os.walk(path):
    print path
    print dirs
    print files
    print "----"
    i += 1
    if i >= 4:
        break

Here are the results:
