whether I expect to be dividing or not. It just saves grief.
If you want division to be floating point.
If, like me, you rarely do floating point
division and want the "/" to mean integer
division as God intended, then you don't
put from __future__ import division in your
source files.
That's one of the good things about Python,
you can have it either way.
Until you someday move up to Python 3, at which point you'll have to go
back and change all your code to use the unambiguous // operator when
you mean integer division. Better to do it now, I think, at least in
any new code you write, to save you the hassle later.
