Support for third-party apps in Siri is still quite limited in iOS 10, and wouldn't work for things like running scripts in response to voice commands. There are a couple of (7, I think) pre-defined extension points available for things like ordering a car (Uber...), booking a table, sending a text message (WhatsApp…) and so on, but none that would fit for Pythonista, so this won't happen anytime soon, I'm afraid.
This is the community forum for my apps Pythonista and Editorial.
