are you sure you need to call this fu 60 times a second? the eye can't see
more than 16 to 20 frames per second. flickering (refresh rate of display)
can be seen for higher rates too but no detail or movements in the picture
are catched by the eye.
i would call python only every second frame.
of course this wasn't your question - just a thought from my side...
some real optimisations:
don't call "range" every time - use a precalculated list with the numbers
or beter iterate as follows:
for sprite in ListOfSprites:
sprite.setPos( 100, 100 )
should save a bit time (no list indexing, no generation of a throw-away
list of indexes).
or even better: don't use "for" use "map" instead:
