# Trying to update the temporal extent description field with Python

I am able to call out and update the temporal extent begin and end dates, but the Description field is also required in ArcCatalog for metadata creation. In my script, I am trying to define it as:

temporal_extent_description = metadata.temporal_extent_description


When I run my script, I do not get any error, and from the Python module in ArcMap, I can call out the field that I inputted by:

print (metadata.temporal_extent_description)


But, if I open the metadata page in ArcCatalog, the box is blank and red indicating that I have not satisfied the required element.

Code that is being submitted in ArcMap:

import arcpy_metadata as md

metadata.title = "There are many variations of passages"

metadata.purpose = "There are many variations of passages..."

metadata.abstract = "There are many variations of passages..."

#TEMPORAL EXTENT DESCRIPTION


"temporal_extent_description": {
