Question

1. Create a 2D numpy array that contains values (4, 3, 1, 33, 21) in the first row values (67, 27, 89, 34, 67) in the second row and values (60, 99, 89, 12, 43) in the third row
   Your code should print the following:

   • [[ 4 3 1 33 21]
     [67 27 89 34 67]
     [60 99 89 12 43]]

2. Write code that prints values [34, 67] [12, 43].
   You must use the colon : based slicing approach to complete this task.
   Your code should print the following:

   • [[34 67]
     [12 43]]

Output:

Code in text format (See above image of code for indentation):

#import numpy module
import numpy as np

#create a list of lists
values=[[4,3,1,33,21],[67,27,89,34,67],[60, 99, 89, 12, 43]]
#create 2D numpy array
ar=np.array(values)
#print array
print("2D Array is:")
print(ar)
print()
#print values using slicing
print(ar[1:3,3:5])
