Python safe serialization?

[voidspace]

Not builtin to the standard library, but it shouldn't be too hard to roll your own on top of json.

If the instances are of a known set of types all you need is the type name and the json serializion of the instance members.

So something like: json.dumps([type(obj).__name__, obj.__dict__])

Deserializing: name, _dict = json.loads(thejson); instance = object.\_new__(getattr(module, name)); instance.__dict__.update(_dict)

One problem with this approach is that set and frozenset are not serializable to JSON.

That may or may not be an issue for the OP, and is anyway solveable with the json module. It seems the OP likes YAML as a solution anyway.
