New submission from Clint Olsen <clint.ol...@gmail.com>:
When I run the following program, I expect args.run to be 'foo' if no argument is specified on the command-line. parser = argparse.ArgumentParser() parser.add_argument('foo', default='bar') args = parser.parse_args() $ ./test usage: test [-h] foo test: error: the following arguments are required: foo However if I specify nargs='*' this error goes away. Maybe I'm missing something obvious, but this seems non-intuitive to me. ---------- components: Library (Lib) messages: 386770 nosy: Clint Olsen priority: normal severity: normal status: open title: Argparse complains argument required when default is provided type: behavior versions: Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue43192> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
