From the PyCon homepage:
PyCon is a community-oriented conference targeting developers (both those using Python and those working on the Python project). It gives you opportunities to learn about significant advances in the Python development community, to participate in a programming sprint with some of the leading minds in the Open Source community, and to meet fellow developers from around the world. The organizers work to make the conference affordable and accessible to all.
We have been honored to present at PyCon on a few occasions. Our presentation content is archived here.
