python - Writing a 3D numpy array to files including its indices -

i'm new apologies have syntax right understand question!
have numpy array shape (2,2,2)

array([[[ 1, 1],         [ 2, 2]],         [[ 3, 3],         [ 4, 4]]])

how write file list indices , array value i.e.

0 0 0 1 1 0 0 3 0 1 0 2 1 1 0 4 0 0 1 1 1 0 1 3 0 1 1 2 1 1 1 4

thanks, ingrid.

a = np.array([[[1, 1],                [2, 2]],                [[3, 3],                [4, 4]]])  items in np.ndenumerate(a):     print(items)

output

((0, 0, 0), 1) ((0, 0, 1), 1) ((0, 1, 0), 2) ((0, 1, 1), 2) ((1, 0, 0), 3) ((1, 0, 1), 3) ((1, 1, 0), 4) ((1, 1, 1), 4)

to remove parentheses can unpack everything

for indexes, value in np.ndenumerate(a):     x,y,z = indexes     print(x,y,z,value)

output

0 0 0 1 0 0 1 1 0 1 0 2 0 1 1 2 1 0 0 3 1 0 1 3 1 1 0 4 1 1 1 4

to handle file writing

with open('file.txt', 'w') f:     indexes, value in np.ndenumerate(a):         x,y,z = indexes         f.write('{} {} {} {}\n'.format(x,y,z,value))
