operations with empty strings | not_equal () function

numpy.core.defchararray.not_equal (arr1, arr2) — this is another function for doing string operations in numpy. It checks the elements of two identical arrays one by one and returns True if they are not equal. Otherwise False is returned.

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.

Code # 1:

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

 
# numpy import

import numpy as geek

 
# input arrays

in_arr1 = geek.array ( ’numpy’ )

print ( "1st Input array:" , in_arr1)

 

in_arr2 = geek.array ( ’nump’ )

print ( "2nd Input array:" , in_arr2) 

  
# check if they are not equal

out_arr = geek.char.not_equal (in_arr1 , in_arr2)

print ( "Output array: " , out_arr) < / code>

Output :

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

Code # 2:

# Python program, explaining
# numpy.char.not_equal () method

 
# numpy import

import numpy as geek

 
# input arrays

in_arr1 = geek.array ([ ’Geeks’ , ’ for’ , ’Geeks’ ])

< p> print ( "1st Input array:" , in_arr1) 

 

in_arr2 = geek.array ([ ’Geek’ , ’for’ , ’ Geek’ ])

print ( "2nd Input array:" , in_arr2) 

 
# check if they are not equal

out_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] 

Code # 3:

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

 
# numpy import

import numpy as geek

 
# input arrays

in_arr1 = geek.array ([ ’ 10’ , ’11’  , ’12’ ])

print ( "1st Input array:" , in_arr1) 

 

in_arr2 = geek.array ([ ’10’ , ’11’ , ’ 121’ ])

print ( "2nd Input array:" , in_arr2) 

 

 
# check if they are not equal

out_arr = ge ek.char.not_equal (in_arr1, in_arr2)

print ( "Output array:" , out_arr) 

Output :

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