It isn't a 'bug in median()' making the wrong assumption about NANs sorting, it is an error in GIVING median a NAN which violates its precondition that the input have a total-order by the less than operator. Asking for the median value of a list that doesn't have a proper total order is a nonsense question, so you get a nonsense answer. It costs too much to have median test if the input does have a total order, just to try to report this sort of condition, that it won't be done for a general purpose operation. -- Richard Damon _______________________________________________ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le...@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/KHXUA6JWCC3LGWTBTQEEGKD6Z22YY345/ Code of Conduct: http://python.org/psf/codeofconduct/
