If you iterate from 1000 to 173, you get nowhere. This is the expected behaviour; this is what a C-style for loop would be written as, it's what range() does, it's the normal thing. Going from a particular starting point to a particular ending point that's earlier than the start results in no iterations. The alternative would be an infinite number of iterations, which is far far worse. ChrisA -- http://mail.python.org/mailman/listinfo/python-list
