python - Is there anything faster than cursor in ArcGIS Desktop to calculate records?

What is the most efficient (fastest) way to calculate records in a layer in ArcGIS?

Is there anything faster than the Cursor in ArcGIS?

Answer

If you are using ArcGIS 10.1 you can use the data access module which speeds up performance and, in my opinion, has a simpler syntax than the traditional cursors. However this module is only available for 10.1 so only use it if you are sure you will not need to run your code in older environments.
