[Tutor] hashlib problems

[Luke Paireepinart]

In general, you shouldn't even hint at the possibility of there being a bug in the code unless you have test cases and a patch handy. Especially something as widely used as hashlib. It  gives An air of arrogance about your post, whether you intend it or not.
I think your issue got resolved already, just thought it might help to have a bit of an explication about hacker culture.
See Eric raymond's how to ask questions the smart way for much more information.  Sad as it is, your initial impressions will actually govern how likely you are to get replies.

Food for thought!
