Code # 1:

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

  

import numpy as geek

 
# input arrays without spaces

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 a string with a space

in_arr = geek.array ([ `Geeks for geeks` , `Code chef` ])

print ( "Input array:" , in_arr) 

 

out_arr = geek.char.isspace (in_arr)

print ( "Output array:" , out_arr)

Exit:

< pre> Input array: [`Geeks for geeks`` Code chef`] Output array: [False False]

Code # 3:

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

 

import numpy as geek

 
# input arrays containing only spaces

in_arr = geek.array ([ ` ` , ` ` , ` ` , ` ` ])

print ( "Input array:" , in_arr) 

 

out_arr = geek.char.isspace (in_arr)

print ( "Output array:" , out_arr)

Output :

 Input array: [`` `` `` `] Output array: [True True True True]
