Update attributes with arcpy.updateCursor and updateRow

Question

I need to update attributes with arcpy.updateCursor and updateRow based on a list of service numbers, but I can't even get one row to update. This is my beginner code.

df= r"GAS FEATURES\SERVICE GROUP\Gas Service Point"  
rows = arcpy.UpdateCursor(df)  
for row in rows:  
   ----if row.getValue("SERVICENUMBER")= '02753-725':     
   ----row.SetValue("SubtypeCD",'Multiple Meter Service')  
   ----rows.updateRow(row)  

Answer 1

Use the data access cursors:

import arcpy

fc = r'C:\data.gdb\somefeature'
fields = ['SERVICENUMBER','SubtypeCD']

with arcpy.da.UpdateCursor(fc,fields) as cursor:
    for row in cursor:
        if row[0] == '02753-725':
            row[1] = 'Multiple Meter Service'
            cursor.updateRow(row)
