Python Numpy Data Analysis Exercises 3

3. Write a Python Numpy program to generate 3x3 array and calculate to find out the difference between maximum and minimum value in x axis.

The output is:

Expected Answer:
3x3 array:
[[0 1 2]
[3 4 5]
[6 7 8]]

Difference between the maximum and the minimum values of the 3x3 array:
[2 2 2]

Sample Answer:

import numpy as np
a = np.arange(9).reshape((3, 3))
print("\n3x3 array:")
print(a)

r1 = np.ptp(a, 1)

print("\nDifference between the maximum and the minimum values of the 3x3 array:")
print(r1)
