A Python Primer for ArcGIS is Finally Out!
It has been a long time coming, but I am finally finished. The Primer came out on December 5, 2011. I must say, this was one of the hardest things I have done. You can get a copy here or through my website at JenningsPlanet.
The American River College online Spring course (Geog 375) is already completely filled, but the book can get you productive.
Hope you enjoy it!
