   @etr2460 Thanks for code review! I follow documentation here:
   https://docs.python.org/2/library/stdtypes.html#dict.get
   and
   https://stackoverflow.com/questions/33263623/dict-getkey-default-vs-dict-getkey-or-default
   
   I would say most of my usage is for the dict that doesn't have key. Why do you think they should be `.get("value") or {}` and `.get("value") or []`?
