sortedcounter
A Counter like the collections class but with sorted keys (thanks to sortedcontainers)
Currently, the only changes to functionality are the replacement of the superclass from dict to sortedcontainer.SortedContainer. Any other changes are cosmetic. I expect that that will remain the case, but I will be adding type/variable annotations where relevant and updating the documentation. At the moment, it is the same as the collections.Counter docs.
This should be a drop-in replacement for a Counter where you need a sorted collection, but as always you should test that first.
Since this subclasses SortedDict, there will be other methods defined than on a dict or a Counter. See the documentation for sortedcontainers for more.
