Like defaultdict? All dicts have been ordered since 3.6.
The comment showing where groipBy, sortBy etc can be found just shows the problem - they are all in different libraries.That's just plain annoying! And don't get me started on the pain of trying to build an Ordered Dictionary with a default initial value!
