I've looked at my Python books "Python Crash Course," "Effective Python,"
and "Python Tricks The Book" as well as web pages in my searches without
finding the answer to what may be a simple question: how to specify a
variable in one file that has its values in another file.

Specifically, how to I designate the salutation holder in the message file
and pass it the name value from the name/email address file?

If this explanation is not sufficiently clear I'll re-write it. :-)

TIA,
