numpy.core.defchararray.not_equal(arr1, arr2) is another function for doing string operations in numpy. It checks the elements of two same shaped array one by one and returns True if they are not equal. Otherwise, it returns False.
Parameters:
arr1 : array_like of str or unicode.
arr2 : array_like of str or unicode.
Returns : [ndarray] Output array of bools, or a single bool if arr1 and arr2 are scalars.

Python3
# 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 equalout_arr = geek.char.not_equal(in_arr1, in_arr2)print ("Output array: ", out_arr) |
Output:

Code #2 :
Python3
# Python program explaining# numpy.char.not_equal() method # 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 equalout_arr = geek.char.not_equal(in_arr1, in_arr2)print ("Output array: ", out_arr) |
Output:
1st Input array : ['Geeks' 'for' 'Geeks'] 2nd Input array : ['Geek' 'for' 'Geek'] Output array: [ True False True]
