[issue46057] argparse: embedded groups may prevent options from being in help output

paul j3 added the comment: "I tried to create a group hierarchy in a way that I can pass the responsibility of argument validation to the argument parser." I looked at your example in: https://bugs.python.org/issue46058 The many levels of nesting groups was confusing, but now I realize tha

László Attila Tóth added the comment: I don't think I'm adventurous as I try to use its public API. If something is public in the pythonic terms (no underscore before it), but undocumented, that can obviously mean two things: either the documentation is outdated or the API published something

paul j3 added the comment: Don't add an argument_group to another argument_group. While input allows this nesting, the formatting is not designed to handle it. Nor does the documentation illustrate such nesting. Nesting a mutually_exclusive_group in an argument_group works because the exc

László Attila Tóth added the comment: my idea regarding _ArgumentGroup,add_argument_group is in the attached file. This doesn't solve the complete help output issue, but addresses the incorrectly called _ArgumentGroup.add_argument_group - a warn() call and return self. As a result the help ou

László Attila Tóth added the comment: According to the documentation only the ArgumentParser has add_argument_group option, which is not true, the code allows me to add a subgroup to any group. The complete example is in issue 4608: https://bugs.python.org/issue46058 If add_argument_group sho

Irit Katriel added the comment: According to the docs it should be >>> xgrp = parser.add_argument_group() rather than >>> xgrp = grp.add_argument_group() This seems to work: >>> parser = argparse.ArgumentParser() >>> grp = parser.add_argument_group('Database settings') >>> grp.add_argum

New submission from László Attila Tóth : I tried to use the following code where the --db-password is not shown in the --help output (Originally I wanted to use mutually exclusive groups but that feature also works strangely, so I changed them to regular groups). def register_db_args(parser: a
