No, "pixel perfect" usually means taking the actual shape
of the object into account, i.e. comparing their bitmaps.
This is obviously a lot more expensive than just comparing
the bounding rects.

Rest assured that Python has no trouble doing integer
arithmetic accurately, and will tell you for certain
whether the bounding rects intersect or not. :-)

(If you were using floats for your rect coordinates,
you might have some accuracy limitations, but that's
a general feature of float arithmetic, and nothing to
do with Python.)
