New submission from Daniel Schulte <trila...@schroedingers-bit.net>:
When calling ArgumentParser.parse_args(list_of_things_to_parse) sys.exit gets called even though the parser was constructed with exit_on_error=False. It doesn't matter if the parser has any subparsers added or not. The docs say > Normally, when you pass an invalid argument list to the parse_args() > method of an ArgumentParser, it will exit with error info. > If the user would like to catch errors manually, the feature can be > enabled by setting exit_on_error to False: > [example code follows] The docs make me believe what I'm trying to do should work. I've attached a minimal working example to show what happens (with and without subparsers). ---------- components: Library (Lib) files: bug.py messages: 410984 nosy: trilader priority: normal severity: normal status: open title: ArgumentParser.parse_args exits on missing required argument with exit_on_error=False type: behavior versions: Python 3.10 Added file: https://bugs.python.org/file50567/bug.py _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue46440> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
