> I am not even sure this is a bug. It really isn't :-) But it is okay to want to improve the traceback. Using _PyErr_FormatFromCause() is plausible, but the resulting traceback is messy. Since there isn't much value in reporting which iterable number has failed, I prefer to just simplify the code with: - if (PyErr_ExceptionMatches(PyExc_TypeError)) - PyErr_Format(PyExc_TypeError, - "zip argument #%zd must support iteration", - i+1); The same change can also be applied to itertools.zip_longest(). ---------- assignee: -> rhettinger components: +Library (Lib) priority: normal -> low versions: +Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue37976> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
