Trouble updating attribute table using arcpy.UpdateCursor

Anonymous User — Tue, 24 Sep 2019 18:17:11 GMT

I am trying to update a column with data from a different attribute table using arcpy.UpdateCursor()

When I run my script it does not return an error, but it does not save the updated value to the table either.

I have attached a screenshot of my code.

Any and all suggestions are greatly appreciated.

My first suggestion is don't use Cursor—Help | ArcGIS Desktop , use UpdateCursor—Help | ArcGIS Desktop.

Also, sharing with Python‌

Hi Hannah,

In your first function, you use an Update Cursor but aren't updating any values. A Search Cursor would be more appropriate. If I understand what you're trying to do correctly, I believe your question is touched upon in some older posts - you can check these two for guidance:
