Thanks @Zeroto521 - LGTM.

Could you also fix or create a follow up issue for DataFrame.nlargest - look inconsistent with others backticks are not correct around the first args: https://pandas.pydata.org/docs/reference/api/pandas.DataFrame.nlargest.html

- `first` : prioritize the first occurrence(s)

Do you mean to add double backticks for first and last, like the following?

-           - `first` : prioritize the first occurrence(s)
-           - `last` : prioritize the last occurrence(s)
+           - ``first`` : prioritize the first occurrence(s)
+           - ``last`` : prioritize the last occurrence(s)
            - ``all`` : do not drop any duplicates, even it means
              selecting more than `n` items.

Yes exactly so they are consistent with the docs here :) @Zeroto521
