Question asked in the facebook python community
#!/usr/bin/env python3
"""
Uma matrix é formada por vetores
Ex:
m = [[1, 1234, 567, 890, 10],
[1, 1234, 567, 890, 10],
[1, 1234, 567, 890, 10]]
Ou, seja:
matrix 3x5 == 3 linha, 5 coluna

Soma valores das duas diagonais principais.
#!/usr/bin/env python3
def diagonal_principal(m):
ac = 0
m1 = []
while ac <= len(m) - 1:
vet = m[ac]
vet[ac] += 1
ac += 1
