Terry J. Reedy added the comment: https://docs.python.org/3/library/functions.html#len * does not specify the exception. In such cases, we occasionally change exception in x.y.0 releases without prior notice other than News and What's New. Also, I think unnecessarily exposing a compile-switch dependent internal detail, as now, is almost a bug. So +1 to applying in 3.7
* The doc does not specify that 'length' cannot be non-negative. Perhaps it should, so no-one will think that they can hijack '__len__' to return something that is not a length, as usually understood. ---------- nosy: +terry.reedy _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue29839> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
