New submission from Matthew Hughes <matthewhughes...@gmail.com>:
>>> import argparse
>>> parser = argparse.ArgumentParser(exit_on_error=False)
>>> parser.parse_args(["--unknown"])
usage: [-h]
: error: unrecognized arguments: --unknown
The docs https://docs.python.org/3.10/library/argparse.html#exit-on-error 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 catch errors manually, the feature can be enable by
> setting exit_on_error to False:
This description _appears_ to be at odds with the observed behavior.
