pymarc – Python MARC record processing (convert MARCXML to MARC)

This will sound very boring to anyone not involved with Library data, but pymarc totally blew my mind the other day. The library – available from https://pypi.org/project/pymarc/ or via  pip install pymarc allows super simple processing of MARC data.
