CODE EXAMPLE FOR PYTHON

3 dimensional array numpy

# required libraries
import numpy as npy

array_3d = npy.array(
    [[[1, 1, 1, 1],
    [1, 1, 1, 1],
    [1, 1, 1, 1]],
    
    [[1, 1, 1, 1],
    [1, 1, 1, 1],
    [1, 1, 1, 1]]])

print(array_3d)
print("Number of dimensions: " ,array_3d.ndim, ", Shape: ", array_3d.shape)
# you can type the array yourself like this
# or you could do somethong like this

ones = npy.ones((2, 3, 4), dtype=int)
print(ones)
print("Number of dimensions: " ,ones.ndim, ", Shape: ", ones.shape)
# and get the same result
