session is a Storage object, which inherits from dict and therefore has all the dict methods. The .get(key, default=None) method is a dict method (i.e., it is not a special method of Storage, which is why it is not explicitly documented) -- it simply gets the value associated with key, and if key does not exist, it returns default. So, session.order.get(id, 0)returns 0 if the requested key doesn't exist in session.order.
