os.walk() is a generator that yields (current directory,
subdirectories, files), and subdirectories and files are lists of
relative names.
(See http://docs.python.org/lib/os-file-dir.html#l2h-1474)

To get the full path of a file or subdirectory while doing a walk, you
can join the name to the current directory (using os.path.join()), and
then use os.path.abspath() on the lot to get the full path (if current
directory is already absolute you don't need that last step).

>>> for d, subs, files in os.walk("."):
print os.path.abspath(os.path.join(d, subs[0]))
break

C:\Python23\BACKUP

On a general note, if you're not sure what something does or the exact
format something is returned in, try playing around with it at the
interactive prompt. If you do:

>>> for item in os.walk("."):
print item
break

...it's pretty easy to see what's going on.
