In my program:

  • I am selecting only schools of the specified type based on the "FACILITY" field and creating new feature class of the result.

  • Deleting records from the resulting feature class from "Select" where the "Verified" field does not equal "Y" or "y" (I need to use: Update cursor and deleteRow method)

  • For the records that do not equal "y" print the name of each deleted school

My code is not deleting the features that are not equal to "Y". And I am not sure how to print out the values that do not equal "Y".

Current error: Traceback (most recent call last): File "C:\Program Files (x86)\Wing IDE 101 4.1\src\debug\tserver_sandbox.py", line 26, in File "C:\Program Files (x86)\Wing IDE 101 4.1\src\debug\tserver_sandbox.py", line 19, in selectSchools TypeError: 'Row' object does not support indexing

    Can you please edit your question and include the error message in full including line numbers. – Midavalo Feb 1 '17 at 15:34

    I suggest you make a sample dataset of a few records and then trim down your code to just the cursor and see if it works. It looks to me like you're mixing the different cursor types. I recommend using arcpy.da.UpdateCursor() rather than arcpy.UpdateCursor(). See ArcGIS Desktop Help - Update Cursor – Midavalo Feb 1 '17 at 15:36

    your if (row[0].upper() != 'y'): block should be indented further – Midavalo Feb 1 '17 at 15:36
  • if (row[0].upper() != 'y'): will always result in true as y is not uppercase – Midavalo Feb 1 '17 at 15:38

Your code doesn't make sense to me, but this is what I think you are trying to do.

  1. Creates new shapefile based on query
  2. Update Cursor runs on new shapefile
  3. If VERIFIED field value isn't Y or y then print the NAME and then delete the record

This code snippet may help you get going

outFile = "output.shp"
fc = "Schools.shp"

query = """ "FACILITY" = '{0}' """.format(sType)
arcpy.Select_analysis(fc, outFile, query)

with arcpy.da.UpdateCursor(outFile, ['FACILITY', 'VERIFIED', 'NAME']) as uCursor:
    for row in uCursor:
        if row[1].upper() != 'Y':
            print row[2]
