If you want an immutable object with a fixed set of fields - not an unreasonable request, mind you - the Python standard library doesn't give you much to work with. NamedTuples are the closest thing we have, but it's so clunky to use that it's not widely used. It's incredibly frustrating, because this leads to external libraries abusing mutable objects everywhere, Django being one of the worse offenders.
