TRANSPOSE OF A MATRIX

The transpose_matrix function computes the transpose of a given matrix.

def transpose_matrix(matrix):

    return [list(row) for row in zip(*matrix)]

 

if __name__=="__main__":

    matrix = [ [1, 2, 3], [4, 5, 6], [7, 8, 9] ]

    print("\n".join(", ".join(map(str, row)) for row in transpose_matrix(matrix)))

Output:

1, 4, 7

2, 5, 8

3, 6, 9
