The slides for my "Python best practices" talk at the "libre software meeting" in Dijon 10 days ago are now online after some minor polishing.
Unfortunately for non-french speakers, they are in french (but with a faire dose of english quotes and technical lingo ;) ) but I hope you will enjoy them anyway.
I don't consider the talk to be finished, there are many more things I'd like to add over time. You're very welcome to send me your comments by email (sf at nuxeo dot com).
I thank Stefan Holek whose talk on "choosing good names" at EuroPython 2005 was an inspiration for this talk.
And, BTW, it's official now:
Pythonic is better than unpythonic ;)
