How do I change the dttm_utc into ISO8601 format with timezone offset?

Answer 1

If your object is a datetime object, you can directly convert it to ISO using obj.isoformat(). If your object is not a datetime object, you can convert it using strptime.

Say, if you were using pandas:

my_obj['dttm_iso8601'] = datetime.datetime.strptime(
        my_obj['dttm_utc'],
        '%Y-%m-%s %h:%m:%s'
    ).isoformat()
