+1 for `collections`, because it's where you look for something similar to Counter. -1 for `statistics`, because the need isn't specific to statistics. It'd be like putting `commonprefix`, which is a general string operation, into `os.path`. It's hacky to import a domain-specific module to use one of its non-domain-specific helpers for a different domain. Someone can argue for functools, as that's the functional programming module, containing `reduce`. _______________________________________________ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
