These new functions were written to follow the existing structure of the idxmin and idxmax functions. Would you like me to parametrize those functions as well so as to not introduce an inconsistency in the testing methodology?

No, he's referring to the fact that you were using nested for-loops for testing. You can avoid those by parametrizing as illustrated here.

Remove these. Refrain from writing anything in the whatsnew until we can agree which version your changes will be applied.

I would rather open an issue that references this and mark it for 1.0. Then the PR can be resurrected at that time. |
git diff upstream/master -u -- "*.py" | flake8 --diffThis PR actually implements the proper behavior for argmax() and argmin() for both Series and DataFrame. We will have to wait to rebase this onto master until after a new release.
