operations with empty strings | isalpha () function

NumPy | Python Methods and Functions | String Variables

numpy.core.defchararray.isalpha (arr) returns True for each item if all characters in the string are alphabetic and there is at least one character; otherwise returns false

Parameters:
arr: array_like of str or unicode.

Returns: [ndarray] Output array of bools.

Code # 1:

       # Python program explaining  
  # numpy.char.isalpha () method  
   
   import   numpy as geek  
   
  # input array  
   in_arr   =   geek.array ([  `abcd`  ,   `ac1bd`  ,  ` abdc`  ,   `dcba`  ,  ` ab cd ` ]) 
   print   (  "Input array:"  , in_arr) 
   
   out_arr   =   geek.char.isalpha (in_arr) 
   print   (  "Output array: " , out_arr)

Output:

 Input array: [`abcd`` ac1bd` `abdc`` dcba` `ab cd`] Output array: [True False True True False]

Code # 2:

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

import numpy as geek

# input array

in_arr = geek.array ([ `geeks` , ` for` , `geeks` , `wow!` ])

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

Exit:

 Input array: [`geeks`` for` `geeks`` wow! `] Output array: [True True True False]
