Actually, division speed hasn't been much of an issue in years.
Arithmetic
has been faster than memory access since CPUs went superscalar. In
CPython,
with all the interpreter overhead, you'll probably never notice the
difference.
I'd thought "xrange" had already been obsoleted, and hadn't realized the
2.3 - 2.6 versions of CPython were still doing "range" the hard way, not
as a generator.
It would've broken some existing code, hence it was left until Python 3.
