When a row is returned from the cursor it is returned as a list of field values that correspond by index position.# state name: row[0] # population: row[1] # print(' has a population of '.format(row[0], row[1]))Tokens can also be used as shortcuts in place of field names.All tables include an Object ID field, which may have many different names depending on the data type.If you only need specific properties of the geometry, use tokens to provide shortcuts to access geometry properties.For instance, Insert and update cursors honor table locks set by Arc GIS applications.
