paul j3 added the comment:
This patch corrects the handling of `seen_non_default_action` in another case -
a positional with '?' and `type=int` (or other conversion).
if
parser.add_argument('badger', type=int, nargs='?', default=2) # or '2'
and the original test 'seen_non_default_actions' is:
if argument_values is not action.default
'argument_values' will be an 'int' regardless of the default. But it will pass
the 'is' test with the (small) int default but not the string default.
With the patch proposed here, both defaults behave the same - 'badger' will not
appear in 'seen_non_default_actions' if it did not occur in the
argument_strings (i.e. match an empty string).
I may add case like this to `test_argparse.py` for this patch.
