Unable to write output from os.path.walk to a file.

[Jeff McNeil]

What exactly are you trying to accomplish? If you're just looking for
the contents of a directory, it would be much easier to simply call
os.listdir(dirinput) as that will return a list of strings that
represent the entries in dirinput.

As it stands, 'os.path.walk' will return None in your example, thus
the reason f.writelines is failing, the error says something about a
required iterable, no?

You ought to look at os.walk anyways, as I believe it is the preferred
approach when walking a directory hierarchy. It's a generator that
will yield a tuple that contains (dirname, subdirectories, filenames).
It seems that is what you're looking for?

Thanks,

Jeff
