Wow!!! Tried this out tonight. Very cool! Obviously that's the way to
do it.

The python reference manual totally sucks. It's incredibly difficult
to find what you want in it and it seems to not even mention lots of
stuff. Maybe it's there, but I can't find it. List comprehensions are
barely mentioned, as far as I can tell. When you do find what you want
to know about, it seems like it's explained in as cryptic a way as
possible.

Aaaaarrrrrggggghhhh!!!

 I looked. Read the above rant.
