*Please* stop worrying about the speed of the compilation here.  If you
have doubts about speed then measure and find the bottlenecks in your code
and iff you find hotspots *then* try to optimize.  But only iff the
program is *to slow*, not when it's fast enough anyway.  In that case you
should always favor more readable code above speed.

Maybe you should work through the tutorial in the Python documentation.
