Used it on a huge project where I wanted the interfaces clean between the Python project at runtime and to serialize the Python objects to the database. Using pickling gave me sleepless night until I moved to Marshmallow. Whilst Django REST Framework comes with a nice serializer and parser modules, marshmallow&#x27;s ability to do just the part was a godsend.<p>This alone gave us the flexibility to expose the Python modules and objects as a simple JSON API and the DB load &#x2F; save came for free.<p>Highly recommended.
