Using PyErr_NewException is fine. You must understand that an
exception is a class, and thus PyErr_NewException creates one for you
and returns it.

Just like you would do with a class that has __dict__, set some
attributes to what you want. That is, use PyObject_SetAttrString or
something more appropriated for you.

In both cases you are just specifying the error message, so you use
what is better for you to provide the error message.
