I 'm trying to run my script but I get this error message.

Here is the code.

import arcpy

env.workspace = r'D:\Eric\Ejercicio\shp\ejercicioTest.gdb\shp'

# Add field to insumo.
arcpy.AddField_management(insumo, "test", "TEXT", "", "", "50", "", "NULLABLE", "NON_REQUIRED", "")
# Make a layer from crbuff to get the select by location works.
arcpy.MakeFeatureLayer_management (crbuff, 'crbuff_layer')
arcpy.MakeFeatureLayer_management (insumo, 'insumo_layer')
# loop with cursor
cursor = arcpy.SearchCursor(crbuff)
field = "Lab" # Specify the field in the loop.
for row in cursor:

Extra bracket in 23.

row.setValue("test", (row.getValue(field))

Change it to: row.setValue("test", row.getValue(field))

Also, consider using arcpy.da.Search/InsertCursor instead of arcpy.Search/InsertCursor, the new (at 10.1) cursors are much faster and have easier and more "pythonic" syntax.

I decided to put this in another question. Thanks.

I'm trying to write in test field from some layer based on iterate feature selction. I get succes using model builder but I'm fail when I try with my own code.

The process with MB.

The code and error.

Any suggestions?

G__EricCastillo_Morales

Thanks Luke. That corrects the syntax problem. Now I get a new problem.

Traceback (most recent call last):

File "D:\Eric\Ejercicio\script\again.py", line 23, in <module>

row.setValue("test", row.getValue(field))

File "C:\Program Files (x86)\ArcGIS\Desktop10.3\ArcPy\arcpy\arcobjects\arcobjects.py", line 1096, in getValue

return convertArcObjectToPythonObject(self._arc_object.GetValue(*gp_fixargs(args)))

RuntimeError: ERROR 999999: Error executing function.

I'm trying to write in "test" field from insumo layer the value field from the select by location features loop of crbuff layer.

In most cases I would recommend using the da cursors, since they are much faster. I can only think of a few use cases for the "old" cursors like accessing the attribute table of the integer raster data set or when using ArcGIS 10.0. There is some more info here: Accessing data using cursors—Help | ArcGIS for Desktop

Luke, nice catch. Also, how do you know when to use arcpy.da.SearchCursor versus using arcpy.SearchCursor?
