Use the built-in serializer in SQLAlchemy:

from sqlalchemy.ext.serializer import loads, dumps
obj = MyAlchemyObject()
# serialize object
serialized_obj = dumps(obj)

# deserialize object
obj = loads(serialized_obj)

If you're transferring the object between sessions, remember to detach the object from the current session using session.expunge(obj). To attach it again, just do session.add(obj).
