Holen Sie sich Diagonalen von 2D -Array

test = [[1,2,3],[4,5,6],[7,8,9],[10,11,12]]

max_col = len(test[0])
max_row = len(test)
cols = [[] for _ in range(max_col)]
rows = [[] for _ in range(max_row)]
fdiag = [[] for _ in range(max_row + max_col - 1)]
bdiag = [[] for _ in range(len(fdiag))]
min_bdiag = -max_row + 1

for x in range(max_col):
