[Tutor] Recursive user input collection problem

[William Witteman]

Thanks to all who responded.  There were several good points about the
code itself, all of which both helped and work.

I will likely use Alan's example because I find it the most lucid, but
the other suggestions are good signposts to other ways to do the same
thing (but right, as opposed to how I was doing it).

Lie's suggestion that I didn't understand the calling structure of
Python was right on the money, and his included link helps with that,
too.  Thanks again.
