All of my scripts have been running fine.</P><P>I am using Python Idle 3.9.18 and getting this code:</P><P>Error 000013: Length of Field Name must not be larger than 10. Failed to execute (Calculate Field).</P><P>Is there something I can do because I have a large number of scripts that use the Add Field and Calculate Field tools and none will run properly anymore because of this code.</P><P>Any other upgrades I need?</P><P>Thank You</P> Tue, 13 Feb 2024 21:58:51 GMT https://community.esri.com/t5/geoprocessing-questions/error-000013-length-of-field-name-python/m-p/1381932#M27162 ModernElectric 2024-02-13T21:58:51Z https://community.esri.com/t5/geoprocessing-questions/error-000013-length-of-field-name-python/m-p/1385338#M27172 <P>The limit for a shapefile field is 10 characters.
