  • "keep getting stuck" is not really a good problem description that we can help with. Please show us your attempt(s). It also helps to show (a tiny part of) your dataframe, and what output you desire. – 9769953 Sep 27 '18 at 09:41

If your question is around how to use the functions map() and np.argmax() together, then here is an example you can refer to, where each row is passed to np.argmax() function using map(). Hope that clears your question.

a = np.array([[2,1,4,5],[7,5,9,8]])

print(list(map(np.argmax,a)))

output: [3, 2]
