Perform the following Multidimensional Dimensional Slicing Operations using Numpy array. array2d = np.array([[1, 2, 3], [4, 5, 6], [7, 8, 9]]). Data science using Python in Anaconda - Jupyter

 Question

1. 2nd and 3rd col

2. 2nd and 3rd row

3. Reverse an array

Program: -

import numpy as np

array2d = np.array([[1, 2, 3], [4, 5, 6], [7, 8, 9]])

print("Orignal Array:- \n",array2d,"\n")

print("2nd and 3rd col :- \n",array2d[:,1:])

print("2nd and 3rd row :- \n",array2d[1:,:])

print("Reverse an array :- \n",array2d[::-1,::-1])

Output: -

Orignal Array:- [[1 2 3] [4 5 6] [7 8 9]] 2nd and 3rd col :- [[2 3] [5 6] [8 9]] 2nd and 3rd row :- [[4 5 6] [7 8 9]] Reverse an array :- [[9 8 7] [6 5 4] [3 2 1]]
