Python is the development language behind many a favourite geek web app. If you want to dive deeper into the world of Python, PyCon AU 2010 — running in Sydney on June 26 and 27 — sounds like a sensible place to be.

Lifehacker plans on attending, if only to be reminded of how sloppy our programming skills have become. Hit the link for more information.
