What is the best way of doing this in Python?

for (v = n / 2 - 1; v >= 0; v--)

I actually tried Google first, but as far as I can see the only solution would be to use while.

    The way to do it is with xrange():

    for v in xrange(n // 2 - 1, -1, -1):
    

    (Or, in Python 3.x, with range() instead of xrange().) // is flooring division, which makes sure the result is a whole number.
