Nathan,
Awesome. Thanks for the re-write! I had indeed thought about collecting all of
the status messages into one message at the end. My Python skills, however, are
still very much in their infancy (only about a week or so), so I was going to
try that next. Now, I can see how you've done it - and learn a bit more! 8^)
I will definitely learn about how to use .append and .extend. I saw them in
some of the docs, but hadn't gotten that far, yet… My only scripting experience
has been with UNIX/IRIX/Linux shell scripts, so this is definitely a step up.
I'm starting to learn just enough about Python to envision that I'll be able to
actually write something useful! Still so much to learn, though… ;^)
Thanks again for taking a look!
Rich
