Type difflib.SequenceMatcher(None, [4] + [5] * 200, [5] * 200).ratio() Don't you get 0 as the answer ? The same with ActivePython on Windows ? Here's a snapshot from my run on a Linux box: Python 2.5.2 (r252:60911, Oct 20 2008, 09:11:31) [GCC 3.4.6 20060404 (Red Hat 3.4.6-10)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import difflib >>> >>> difflib.SequenceMatcher(None, [4] + [5] * 200, [5] * 200).ratio() 0.0 Executing exactly the same steps, do you not get 0.0 ? -- http://mail.python.org/mailman/listinfo/python-list
