What are the steps to create 1D, 2D and 3D arrays?

1D array creation:

import numpy as np

one_dimensional_list = [1,2,4]

one_dimensional_arr = np.array(one_dimensional_list)

print("1D array is : ",one_dimensional_arr)

2D array creation:

import numpy as np

two_dimensional_list=[[1,2,3],[4,5,6]]

two_dimensional_arr = np.array(two_dimensional_list)

print("2D array is : ",two_dimensional_arr)

3D array creation:

import numpy as np

three_dimensional_list=[[[1,2,3],[4,5,6],[7,8,9]]]

three_dimensional_arr = np.array(three_dimensional_list)

print("3D array is : ",three_dimensional_arr)

ND array creation: This can be achieved by giving the ndmin attribute. The below example demonstrates the creation of a 6D array:

import numpy as np

ndArray = np.array([1, 2, 3, 4], ndmin=6)

print(ndArray)

print('Dimensions of array:', ndArray.ndim)
