I can add a new one to his list. I was getting error messages on setting gp.workspace = 'foo' where ''foo'' is a valid path. It's because the gp object was hanging around in pythonwin's memory. You should be able to say 'del gp' but I gave up and restarted pythonwin to fix it. | |||

How about geoprocessing with OGR/GDAL? Will that do it for me?
Getting Python 2.4 and GDAL without disrupting the ESRI installation... See also Howard Butler's site.
Not good enough: FWtools installs a funky GUI called OpenEV_FW and a shell environment. It comes with python 2.3.4 which is old but better than ESRI's 2.1 It does NOT include the pythonwin IDE. How INCORNVENIENT!
23-Aug-2006 Python+OGR probably not worth messing with right now. From the OGR site: The Python API isn't really well documented at this time, but parallels the C/C++ APIs. The interface classes can be browsed in the pymod/ogr.py (simple features) and pymod/osr.py (coordinate systems) python modules. The pymod/samples/assemblepoly.py sample script is one demonstration of using the python API.
