New submission from paul j3: The documentation for Mutual exclusion
https://docs.python.org/3/library/argparse.html#mutual-exclusion needs a note that a mutually exclusive group may contain one positional argument. But that argument must be either nargs='?', or nargs='*'. If '*' it must also have a default parameter (other than None). (this issue came up recently on stackoverflow. It may have also been raised in the past as a bug/issue, but I don't have time at moment to search. I had to search through several layers of code to remember all the details.) http://stackoverflow.com/questions/35044288/how-can-i-create-an-argparse-mutually-exclusive-group-with-multiple-positional-p ---------- assignee: docs@python components: Documentation messages: 259179 nosy: docs@python, paul.j3 priority: normal severity: normal status: open title: argparse docs: Positional * argument in mutually exclusive group requires a default parameter versions: Python 3.6 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue26235> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
