FYI, dicts are now ordered by default as of Python 3.6.

  That's an implementation detail, and shouldn't be relied upon. If you want an ordered dictionary, you should use collections.OrderedDict.

    True, but if you need both key ordering and performance, dict is the better option.

    It's now the spec for 3.6+. > #python news: @gvanrossum just pronounced that dicts are now guaranteed to retain insertion order. This is the end of a long journey. https://twitter.com/raymondh/status/941709626545864704 https://twitter.com/raymondh/status/941709626545864704 More here: https://www.reddit.com/r/Python/comments/7jyluw/dict_knownordered_versus_ordereddict_an/ https://www.reddit.com/r/Python/comments/7jyluw/dict_knownor...
