LOL, it's actually on the list of things to do. And hear that one will become a
better programmer once they learn LISP.

I am always fighting the battle - more compact vs more readable :) . A couple of
questions that I have: Why generators over map? Is it somehow more efficient
under the covers or is it for readability purposes? I noticed that you
took out the
lambda function too (not much good without a map/filter/reduce) to replace
with the generator function. Also could you give me some instances
where a generator
would be used in a real situation? I have already read the stuff on
doc.python.org about
generators.
Thanks,
Tino
