Numpy get secondary diagonal with offset=1 and change the values

Question

I have this 6x6 matrix filled with 0s. I got the secondary diagonal in sec_diag. The thing I am trying to do is to change the values of above the sec_diag inside the matrix with the odds numbers from 9-1 [9,7,5,3,1]

import numpy as np
x = np.zeros((6,6), int)
sec_diag = np.diagonal(np.fliplr(x), offset=1)

The result should look like this:

[[0,0,0,0,9,0],
 [0,0,0,7,0,0],
 [0,0,5,0,0,0],
 [0,3,0,0,0,0],
 [1,0,0,0,0,0],
 [0,0,0,0,0,0]]

EDIT: np.fill_diagonal isn't going to work.

Answer 1

Maybe you should try with a double loop
