TypeError: rename() got an unexpected keyword argument "axis"Problem description
Sure, it is redundant, but for compatibility it would be good to support it.
In particular, I have an old method which calls obj.rename_index(axis=n) with obj sometimes being a DataFrame and sometimes a Series, and now I get a warning asking me to use rename... but if I do, I get the above error.
Expected Output
The same as without axis=0.
