paul j3 added the comment: At the very least the `is not action.default` needs to be changed. Else where in argparse `is` is only used with `None` or constant like `SUPPRESS`. So using it with a user defined parameter is definitely not a good idea.
Possible variations on how `is` behaves across implementations (pypy, ironpython) only complicates the issue. I'm also familiar with a Javascript translation of argparse (that uses its `!==` in this context). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue18943> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
