How does this next work?

[Pedroski55]

Using next() with os.walk() I can very neatly and easily get all files in a folder and ignore other folders if present.

I have to say, I don't really understand what's happening, but it works great!

files = next(os.walk(path2talkfiles))[2]
files.sort()

Could someone elaborate a little?

os.walk(path2talkfiles) is an iterator. It behaves like a sequence of tuples

Output:
(root, dirs, files)
(root, dirs, files)
(root, dirs, files)
(root, dirs, files)
(root, dirs, files)
(root, dirs, files)
...

The next() function returns the next item of an iterator and advances the iterator. In this case it returns the first tuple (root, dirs, files). Taking the [2] element in this tuple is a list of files in the root directory.
