I believe that the current behavior of `statistics.median[|_low|_high\]` is simply broken. It relies on the particular behavior of Python sorting, which only utilizes `.__lt__()` between objects, and hence does not require a total order. I can think of absolutely no way to characterize these as reasonable results: Python 3.7.1 | packaged by conda-forge | (default, Nov 13 2018, 09:50:42) >>> statistics.median([9, 9, 9, nan, 1, 2, 3, 4, 5]) 1 >>> statistics.median([9, 9, 9, nan, 1, 2, 3, 4]) nan ---------- nosy: +David Mertz _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue33084> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
