numpy string operations | isspace() function

Last Updated : 15 Jan, 2019

numpy.core.defchararray.isspace(arr) function returns true for each element if there are only whitespace characters in the string and there is at least one character.It returns false otherwise.

Syntax: numpy.core.isspace(arr)

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]
