Working on fixing the argparse test failure.

Updated the tests, all passed on local Ubuntu!

Updated the tests, all passed on local Ubuntu!

However, when I fix test file it needs make patchcheck, when I do patchcheck whitespaces just get broken.
Don't know what to do at this point, it's like an endless-loop.

I checked the last commit on this file(test_argparse.py). It was eafec26 , it doesn't seem like the same issue occurred there. So, we might have to check if make patchcheck has somehow changed recently.

I can't see the output of that commit's build either. So can't look into it for any clue.

Also there is another solution to just use self.dict and ignore container, it gives the same list and seems to be better than creating and updating the list manually.

But internal names could be picked up by mistake, so an explicit list seems fine to me.
(Although unwanted names would break tests, so the mistake could be fixed. But I prefer to keep the original author’s code here.)

Thanks for the PR. Because the code here is the same as #91841, I am closing this one so that reviews and approvals stay in one place. The contribution is appreciated nonetheless!
