I know that in the terminal it represents

for filename in filenames:

I know that in the terminal it represents the last printed text.

The underscore is no magic here. It's just a conventional variable
name, saying "I m unused". One could also write:

It's not magic at all. _ is just a variable name. When someone names a

Thank you to everyone for your help.
Much appreciated. I now have a better understanding of how glob can be
used and I have a much better understanding of using the more
effective os.walk.

No, os.path.walk will always recurse through all of the sub, that's
its purpose. os.walk produces a generator, which you can then manually

Your args are fine, that's just the way os.path.walk works. If you
just need the absolute pathname of a directory when given a relative
path, you can always use os.path.abspath, too.
A couple more examples that may help, using os.walk:

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 retu

Opps. I missed the "path", so gave an answer for os.walk. Apologies.

Assuming that processDirectory is a function of yours that returns a bool,
then you'd do something like:
