dict is good, but `accum` can be generalized, see <a href="https://py.checkio.org/mission/sum-by-type/publications/flpo/python-3/resultgetstr-resultgetint-0/">my creative</a> :)

Of course it can. See <a href="https://py.checkio.org/mission/sum-by-type/publications/veky/python-3/neutraldict/">my creative</a>. :-D

Quite interesting to see the way of dict() being used. TIL.

I'm glad you learned, but there's no `dict()` above... only `str()` and `int()`.

Like the expandability of this solution while also remaining clear :)

The expandability is even greater <a href="https://py.checkio.org/mission/sum-by-type/publications/veky/python-3/neutraldict/">here</a>. The clarity, well... :-]
