Updating some python code from 9.3 that using geoprocessing to 10.0 using arcpy and the first real object I’ve had to change relates to detecting whether or not an index exists on a table. I previously posted code using a 9.3 geoprocessing commands, the core of it being: indexList = gp.listindexes(tablename) for iIndex in indexList: if (iIndex.Name == indexname): return True return False With arcpy, ESRI has gone back to using the Describe methodology.
