__dict__ vs to_dict()

Hey, this might be a strange thing to open an issue for, but I'm using the SDK to transition from Authorize.net AIM to CyberSource, and I noticed that all the examples use things like:

request.payment_information = payment_info.__dict__
# etc
message_body = json.dumps(request.__dict__)

instead of:

request.payment_information = payment_info
# etc
message_body = json.dumps(request.do_dict())

...even though the SDK provides to_dict() for a whole lot of things, so it looks like it was designed for that (and it avoids including unwanted attributes by accident). It looks like both ways produce the same output and work on the process_payment.py sample.

Is there a reason to prefer __dict__ each time over a single to_dict() at the end?

Thanks

Iniziate con l’esempio process_payment.py e gli oggetti SDK che espongono to_dict(); confrontate i due percorsi di serializzazione descritti nell’issue. Il lavoro sarebbe completato con una raccomandazione confermata da un maintainer e, se gli esempi dovessero cambiare, con un aggiornamento della documentazione o dell’esempio chiaramente identificato; l’issue non indica alcun file di destinazione né alcun test.
