operaciones de string numpy | función not_equal()

numpy.core.defchararray.not_equal(arr1, arr2) es otra función para realizar operaciones de string en numpy. Comprueba los elementos de dos arrays de la misma forma uno por uno y devuelve True si no son iguales. De lo contrario, devuelve False .
 

Parámetros:  
arr1: array_like de str o unicode. 
arr2 : array_like de str o unicode.
Devuelve: [ndarray] Array de salida de bools, o un solo bool si arr1 y arr2 son escalares.

# Python program explaining
# numpy.char.not_equal() method
 
# importing numpy
import numpy as geek
 
# input arrays 
in_arr1 = geek.array('numpy')
print ("1st Input array : ", in_arr1)
 
in_arr2 = geek.array('numpy')
print ("2nd Input array : ", in_arr2) 
 
# checking if they are not equal
out_arr = geek.char.not_equal(in_arr1, in_arr2)
print ("Output array: ", out_arr)

1st Input array :  numpy
2nd Input array :  nump
Output array:  True

# importing numpy
import numpy as geek
 
# input arrays 
in_arr1 = geek.array(['Geeks', 'for', 'Geeks'])
print ("1st Input array : ", in_arr1)
 
in_arr2 = geek.array(['Geek', 'for', 'Geek'])
print ("2nd Input array : ", in_arr2)
 
# checking if they are not equal
out_arr = geek.char.not_equal(in_arr1, in_arr2)
print ("Output array: ", out_arr)

1st Input array :  ['Geeks' 'for' 'Geeks']
2nd Input array :  ['Geek' 'for' 'Geek']
Output array:  [ True False  True]

print ("Output array: ", out_arr)

1st Input array :  ['10' '11' '12']
2nd Input array :  ['10' '11' '121']
Output array:  [False False  True]
