The word 'default', used to indicate default arguments in the help text (found here: Lib/argparse.py:681) is missing the gettext wrapper, causing it to be untranslatable.

Note: the line number in the link is not correct anymore, I'm not sure how to link to a specific commit so here is the source line:
help += ' (default: %(default)s)'.tirkarthi commentedon Apr 6, 2019
@paul.j3 I assume this is an easy issue of wrapping "default" with _() at [0]. There doesn't seem to be any tests for localization in argparse.
cpython/Lib/argparse.py

I haven't paid much attention to the localization issues in
argparse.The issue is with the help modification done by the:
class ArgumentDefaultsHelpFormatter
This formatter is a convenience, not something critical. The programmer could always include that 'default' string in the help line with their preferred terminology. They don't have to use this formatter to show the default values in their help lines.
_() is used mostly for error messages with the format
So the following change might work:
But I'm not in a position to test it or evaluate its usefulness.

points out that the 'version' action isn't localizable either.
