how to create 3 dimensional array in 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

two dimensional array python

# Creates a list containing 5 lists, each of 8 items, all set to 0
w, h = 8, 5;
Matrix = [[0 for y in range(h)] for x in range(w)] 

Matrix[0][0] = 1
Matrix[0][6] = 3 # error! range... 
Matrix[6][0] = 3 # valid

how to create multidimensional array in python using numpy

from numpy import *
array = array([[1,2,3,4],[3,4,2,5]])

## if want you can print it 
print(array)
