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]
