Hello System Windows Vista / ArcGIS 9.3I have ten shape files.Each of them has the fields starting with D in the attribute table. (D8739, D1983)Some have 10 D fields, and other have about 20.Now I want to delete the D fields using python.However, no D field was deleted after running the code below.Please kindly help to modify it and thank you in advance##Script Name: calculate sum ##Description: calculate sum of merged range sizes of a taxonomy of migratory birds ##Created By: Elaine Kuo ##Date: 26/05/2012 #Import standard library modules import arcgisscripting import os #Create the Geoprocessor object gp = arcgisscripting.create(9.3) #Set the workspace. gp.Workspace= "H:/temp_D/test_1" #gp.Workspace= "H:/temp_stage_2_3_polygon_limit_1984_no_R_O/P_Turdidae_22" #Set the workspace.
