>> But I wonder, was this situation discussed in the original bug/issue? >Doesn't look like it: I was looking at the wrong PR link. This has more discussion: https://github.com/python/cpython/pull/13305. nargs is discussed but I'm not sure it was realized that the nargs=None and nargs="?" cases would act in the way seen here rather than acting like append. Having a default nargs of "+" was suggested but that suggestion was not addressed. > I suggest that the default nargs for extend should be "*" or "+" and an > exception should be raised if nargs is given as "?". I'm not convinced about that any more. Using append's behaviour is probably more reasonable for nargs=None and nargs="?". ---------- nosy: +Anthony Sottile, BTaskaya, berker.peksag _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue40365> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
