[jbrockmendel]

• closes #xxxx (Replace xxxx with the GitHub issue number)
• Tests added and passed if fixing a bug or adding a new feature
• All code checks passed.
• Added type annotations to new arguments/methods/functions.
• Added an entry in the latest doc/source/whatsnew/vX.X.X.rst file if fixing a bug or adding a new feature.

Improves the patch-job done by #38742. Also makes the affected test robust to always-distinguish NAN-vs-NA behavior.

Looks like 87d5fdf undid all your changes before

[jbrockmendel]

Woops. Looks better now.

ruff format.............................................................................................Failed
- hook id: ruff-format
- files were modified by this hook

Any idea how to make it tell me what it wants to change?

[mroeschke]

You can comment pre-commit.ci autofix in this PR to get pre-commit to add a commit to fix it for you.

Otherwise if you have the pre-commit hooks installed, to show the fixes you'll probably need to add --show-fixes on this line

pandas/.pre-commit-config.yaml

Line 25 in 8475758

args: [--exit-non-zero-on-fix]

[jbrockmendel]

running ruff format locally on the affected files says it leaves them unchanged

[mroeschke]

What about running pre-commit run ruff --all-files? (Generally pre-commit run <id to check> is the source of truth for the linting checks)

[jbrockmendel]

That did it, thanks. Lets see if the CI agrees

[jbrockmendel]

Booyah, did it. Thanks for help troubleshooting

[mroeschke]

Np! Thanks @jbrockmendel
