Python's version for Object Model Diagram

BaileyLipscomb1 — Wed, 28 Mar 2012 19:29:03 GMT

When I was taught ArcObjects, an object model diagram was in existence.

I am now using Python. Is there anything similar to the object model diagram for Python. I looked at the documentation starting on this page: http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/What_is_ArcPy/000v000000v7000000/

However, this section on arcpy does not appear to cover all functions, classes etc.

Can someone point me to a full documentation of arcpy?

No such official document exists.

No such official document exists.

So there's no place to get a full listing of arcpy functions, classes, and modules?

That is just a photoshopped version of the 9.3.1 GP model. A lot changed in the arcpy module, enough that I would consider following that diagram a bad idea.

In a word... No.

It's not complete, but have you seen this: http://forums.arcgis.com/threads/50806-ArcPy-Geoprocessor-OMD-v10-Unofficial

While I wouldn't call it documentation exactly, the Python auto-complete function is pretty helpful to give you an idea of what's available in terms of methods and properties - even tool syntax.

Besides, why would anyone want an easy to use reference document that, say, you could print and "look at"?

I think many (all?) of us are really rooting for ESRI to change their minds and publish an arcpy OMD for v10.1.

Yes, see the ArcGIS 10 help. Particularly the ArcPy site package, but see also Geoprocessing with Python, Geoprocessing environment settings and the Geoprocessing tool reference.

Start Pythonwin then type

then type

then choose what you want and type
