After reading 


I would guess that the second argument has to be a list of field names, i. 

updCursor = arcpy.UpdateCursor(
    ["POINT_X", "POINT_Y"],

The goal of the tutor mailing list is to help newbies with the Python 
language, the standard library, and common external packages.

As yours is a specialist topic you will most likely get better answers when 
you ask questions concerning arcgis on a dedicated mailing list or forum.
