Thanks, Zach! About the time your reply arrived I was starting to
realize that my '#1' or '#2' might not be doing what I thought. In the
"Python Pocket Reference" I was just looking at:

X or Y     If X is false then Y; else X.

I forgot that different languages have different interpretations of "or".
