I need to save this data and print it back into a matrix and use it. .txt not required. — Gizli Zihin

Reshape it to 2d, and use savetxt and genfromtxt. Resahape again. There's no standard for 3 or 4d array text. — hpaulj

Since you say you don't need to save it as a .txt file, you can save it to a .npy like so:

import numpy as np

arr = np.zeros((61, 33, 2, 7))
np.save('/path/to/some/directory/some_file.npy', arr)
