Typically for serializing Python objects you would use pickle . The
'dumps' function returns a string (make sure you use the text protocol
You could then execute code inside the Python engine to serialize /
deserialize objects. I've not tried this for instances that inherit from
C# base classes - but it should work fine. :-)
