Find index of the last occurence for maximal value in pd.DataFrame

Question

I need to find argmax index in pd.DataFrame. I want exacly the same result, as pandas.DataFrame.idxmax does, but this function returns index of first occurrence of maximum over requested axis. I want find index of last occurrence of maximum. Thank you in advance.

Run df[::-1].idxmax()

The trick is to process rows in reversed order.
