Here's a quick example. (And, by the way, please try to avoid the sort 
of double-spacing above, especially if you're coming from Google Groups 
which tends to produce such effects).

This should walk down the Python directory, creating a text file for 
each directory. The textfile will contain the names of all the files in 
the directory. (NB this might create a lot of text files so run it 
inside some temp directory).

<code>
import os

root = "c:/temp"

for dirpath, dirnames, filenames in os.walk(root):
     print("Looking at", dirpath)
     txt_filename = os.path.basename(dirpath) + ".txt"
     with open(txt_filename, "w") as f:
       f.write("\n".join(filenames))

</code>
