Last Updated : 14 Jan, 2019

numpy.core.defchararray.isupper(arr) function returns True for each element if all cased characters in the string are uppercase and there is at least one character, it returns false otherwise.

Parameters: arr : array_like of str or unicodeReturns : [ndarray] Output array of bools.

Code #1:

Python Program explaining

numpy.char.isupper() function

import numpy as geek

in_arr = geek.array(['P4Q R', '4Q rP', 'Q rp4', 'rpq']) print ("input array : ", in_arr)

out_arr = geek.char.isupper(in_arr) print ("output array :", out_arr)

`

Output:

input array : ['P4Q R' '4Q rP' 'Q rp4' 'rpq'] output array : [ True False False False]
