附加信息
The issue is fixed in the ArcGIS Pro 3.1 release. To protect backward compatibility, the default behavior remains as is, but there is a new keyword argument for da.UpdateCursor and da.InsertCursor to allow explicit overriding of default values with null.解决办法
Use the old update cursor or use the Calculate Field geoprocessing tool.
def workaround0():
rows=arcpy.UpdateCursor(os.path.join(geodatabase, fcName))
for row in rows:
row.intField = None
rows.updateRow(row)
def workaround1():
arcpy.CalculateField_management(os.path.join(geodatabase, fcName), 'thisField', 'getNone()', 'PYTHON_9.3', r'def getNone():\n return None')
