True. It's far too verbose. I'd go for something like:
f=lambda n:n<=0 or n*f(~-n)
I've saved a few precious keystrokes and used the very handy ~- idiom!
Huh, I've never seen that one before. Seems to work on both positive and

The ~- trick only works on two's complement numbers. I've worked on
machines in the past that used one's complement, and this wouldn't work
there.
