FWIW, I think that by convention _ is an alias for a translation
function.  In other words, this message is marked as one that is
translatable.  I'm only guessing, but I've run into this in some UI code
in Python I've seen.

By the way, I would like to say that I am somewhat of a newbie to
Python, and also that I really appreciate the knowledge I've picked up
on this list thus far.  To all those of you who take time out of your
busy day to answer questions, thank you!
