Unravel Index

import numpy as np

a = np.array([
    [1,2,4,7],
    [9,88,6,45],
    [9,76,3,4]
])

a

array([[ 1,  2,  4,  7],
       [ 9, 88,  6, 45],
       [ 9, 76,  3,  4]])

np.unravel_index(np.argmax(a), a.shape)

(1, 1)

The above line will get you the maximum value’s coordinate. In our case 88’s position

np.argmax(a)
