While I am not a part of our GIS department, they use ArcGIS which has
Python support built in. If that's what you're using, you should be
able to use the examples given on ESRI's website:

Hmmm...not much there. Here are some other links I found:

http://nrm.salrm.uaf.edu/~dverbyla/arcgis_python/index.html
http://www.ollivier.co.nz/publication/uc2004/python_workshop /sld008.htm
http://www.3dartist.com/WP/python/pycode.htm

I don't know if these will be much help. You really need to just dig
in and start coding. I would recommend "Programming Python 3rd Ed." by
Lutz if you want something in hard copy. "Dive Into Python" is a free
book that's online that I'm told is very good. Both have good
examples, some of which are involved. All the web oriented Python
books are a few years old, but the code in them still works, for the
most part.
