(i.e. such as the API here: https://multiset.readthedocs.io/en/stable/). It seems that’s just what you want. Honestly, despite the idea of “batteries included”, it is very common these days to need a third party lib. If that package meets your needs, then great. If it’s lacking in some way, then suggest (better yet, contribute) improvements. If you still think that package, or something like it, should be in the stdlib, Then you’ll need to make the case that it’s a commonly enough used feature to justify addition to the stdlib. For my part, I don’t think I’ve ever had a need for a multiset - so a third party lib is fine. I have no idea if I’m unusual, but that’s the case you’d need to make. -CHB -- Christopher Barker, PhD (Chris) Python Language Consulting - Teaching - Scientific Software Development - Desktop GUI and Web Development - wxPython, numpy, scipy, Cython
