My reply was obviously tongue in cheek, triggered by Chris Rebert's "code golf" remark. using ~-n instead of n-1 if obfuscatory and doesn't even save keystrokes! (Although it could in other situations, e.g 2*(n-1) can be written 2*~-n, saving two brackets.) -- Arnaud -- http://mail.python.org/mailman/listinfo/python-list
