What is interesting is that the latest 2.4 Python docs say that walk() returns a Tuple, which is untrue. It returns a generator object according to type(). This had me heavily confused as to how to use what was returned from walk() and it took a good hour of troubleshooting to figure it out.
The docs are correct but maybe a little subtle. They say,
walk( top[, topdown=True [, onerror=None]])
walk() generates the file names in a directory tree, by walking the tree either top down or bottom up. For each directory in the tree rooted at directory top (including top itself), it yields a 3-tuple (dirpath, dirnames, filenames).
To someone familiar with Python generators, the words "generates" and "yields" are strong clues that walk is a generator and when you iterate over it you get tuples. If you are not familiar with this terminology I can see how it would be confusing.
OTOH there are two examples in the same section that show correct usage...
