Is it just me or is dict#setdefualt a terribly named function? I just learned of it here, and I was excited that it would set the default value for the dictionary, when instead it performs something like:

  (self, key, default) => self[key] = (key in self ? self[key] : default)

I'd prefer something like "dict#createifnotexists", but better.

Are you maybe looking for a defaultdict? https://docs.python.org/3.7/library/collections.html#collect...

I'm aware of defaultdict, but when I saw that method on dict I got excited because I thought it meant I didn't need defaultdict anymore.

Or get_or_create, to follow Django's example.
