Walking recursivly through a directory-structure

[bragib at my-deja.com]

Hallo Paal:

You are on the right track... Just use os.path.walk(path, visit, arg)
You should write the visit function yourself.  Calls the function visit
with arguments (arg, dirname, names) for each directory in the directory
tree rooted at path (including path itself, if it is a directory).

So for instance if you would had a directory tree like this
/home/bragi/tmp2/
    /home/bragi/tmp2/file1.dat
    /home/bragi/tmp2/file2.dat
    /home/bragi/tmp2/file3.dat
      /home/brag/tmp2/dir2/file1.dat
      /home/bragi/tmp2/dir2/file2.dat

and you want to make a dictionary keyed by the directory name and the
dictionary values being the files in that dictionary.

import os, posixpath
dirContents = {}
def visit(arg, dirname, names):
    files = []
    for name in names:
        if os.path.isfile(name): # keep if file
            files.append(name)
    dirContents[dirname] = files
arg1 = 'Hello'
arg2 = 'World'
os.path.walk('/home/bragi/tmp2', visit, (arg1, arg2))
print dirContents

Your output would be:
{'/home/bragi/tmp2': ['file2.dat', 'file3.dat', 'file1.dat'],
'/home/bragi/tmp2/dir2': ['file2.dat', 'file1.dat']}
