Not at all.  Do you object to my use of lambdas?  I'm not aware of
anything that says it's bad form to define a function using a lambda
when the only thing that a function does is immediately return some
calculated value.

I wasn't aware of either "any" or "all".  Thanks for the info!
Unfortunately this recent project where I used "min" and "max" is
running on a system using Python 2.4, so "any" and "all" are not
available.

I haven't used sets very much, but I'll definitely keep this in mind.
Thanks!
