Return value:

out : ndarray - Output array of str or unicode, depending on input types.

Example-1: numpy.char.capitalize() function

>>> import numpy as np
>>> x = np.array(['a1b2','1b2a','b2a1','2a1b']);

Example-2: numpy.char.capitalize() function

import numpy as np    
a1 = 'python tutorial'
a2 = 'python exercises'
  
print ("a1: ", a1) 
print ("a2: ", a2) 
  
print("\nArray data after using capitalize():") 
print ("a1: ", np.char.capitalize(a1)) 
print ("a2: ", np.char.capitalize(a2)) 

Output:

a1:  python tutorial
a2:  python exercises

Array data after using capitalize():
a1:  Python tutorial
a2:  Python exercises
