You get my prize 'Zero' for best answer!

[You've also given me a nice example for my next python class -- I
usually spend time showing how to play in the interpreter.  And the
examples I usually give are numeric/string/list based. Short-circuit
evaluation is good to show. So thanks]

Incidentally, you have also proved right Nicolas' claim that this is
helpful to all :-)  All that is needed is that other charitable-to-
Nick souls on this list should exercise some restraint and provide the
answers that they *know* he *needs* rather than what he *claims* to
*want*.
