need help with UpdateCursor and .updateRow(row)!!!

Question

Hi all,

I am studying python scripting for geoprocessing and am having trouble with a update cursor loop.

"Property_Layer" is a feature layer and I want to narrow the arcpy.UpdateCursor to empty "LOCALITY" fields. I then want to use the for loop to set the "LOCALITY" field to the variable "value".

my code stalls at the rows.updatRow(row) line. I'm not sure I can use a feature layer with the UpdateCursor....!?

I am new to this so any help would be greatly appreciated!

rows = arcpy.UpdateCursor ("Property_Layer",'"LOCALITY" = ' + "'" + "'")

row = rows.next()
         
        for row in rows:            
            row.setValue ("LOCALITY", value)            
            rows.updateRow(row)
            
            del row, rows   #delete cursors

I think Chris meant to indent the line for updateRow...

Here is the correct syntax to create an update cursor to help you started
import arcpy

def UpdateField(value):
    # Create update cursor for your feature class
    # Update the correct path to your feature layer
    rows = arcpy.UpdateCursor(r"C:\Temp	est.gdb\Property_Layer")

# Update/calculate field to the variable "value"
    for row in rows:
        # Update "LOCALITY" Field
        row.LOCALITY= value
        rows.updateRow(row)
    # Delete cursor and row objects to remove locks on the data
    del row
    del rows

Then you can call this UpdateField() function and pass a variable with a value that you want to calculate the field to.
