Python Row, Column, Matrix Trouble

I'm writing a python program with with a given matrix = [['A', 'B', 'C'], ['D', 'E', 'F'], ['G', 'H', 'I']] I'm trying to write a code so that I can define

Solution 1:

You can always try this,

def getLoc(matrix, elem):
    row , col = 0 , 0
    for a in [j for i in matrix for j in i]:
        if a == elem:
            return row / len(matrix), col % len(matrix)
        col += 1
        row += 1
