Hello, I need some help with this script I am developing. I need the update cursor to overwrite the empty LOCALITY values in TWB_Property with the ADMINAREA from TWB_Suburbs that I have turned into a list. I know the code is a little messy and I also can not figure out how to display it all using this forum. Any help will be appreciated. Thank you. code begins below. # Import modules
