Parameters:
arr : array_like of str or unicode.

Returns : [ndarray] Output array of bools.

Code #1 :

# Python program explaining
# numpy.char.isspace() method

import numpy as geek

# input arrays  not containing any space
in_arr = geek.array([ 'Geeksforgeeks', 'Codechef'] )
print ("Input array : ", in_arr)

out_arr = geek.char.isspace(in_arr)
print ("Output array: ", out_arr)

Output:

Input array :  ['Geeksforgeeks' 'Codechef']
Output array:  [False False]

Code #2 :

# Python program explaining
# numpy.char.isspace() method

import numpy as geek

# input arrays containing string along with space
in_arr = geek.array([ 'Geeks\nfor\ngeeks', 'Code\tchef'] )
print ("Input array : ", in_arr)

out_arr = geek.char.isspace(in_arr)
print ("Output array: ", out_arr)

Output:

Input array :  ['Geeks\nfor\ngeeks' 'Code\tchef']
Output array:  [False False]

Code #3 :

# Python program explaining
# numpy.char.isspace() method

import numpy as geek

# input arrays containing only white space
in_arr = geek.array([ '\n', '\t', ' ', '\n\t '] )
print ("Input array : ", in_arr)

out_arr = geek.char.isspace(in_arr)
print ("Output array: ", out_arr)

Output:

Input array :  ['\n' '\t' ' ' '\n\t ']
Output array:  [ True  True  True  True]
