Write a NumPy program to count the number of days of specific month

import numpy as np
print("Number of days, February, 2016: ")
print(np.datetime64('2016-03-01') - np.datetime64('2016-02-01'))
print("Number of days, February, 2017: ")
print(np.datetime64('2017-03-01') - np.datetime64('2017-02-01'))
print("Number of days, February, 2018: ")
print(np.datetime64('2018-03-01') - np.datetime64('2018-02-01'))

Sample Output:

Number of days, February, 2016:                                        
29 days                                                                
Number of days, February, 2017:                                        
28 days                                                                
Number of days, February, 2018:
