operations with empty strings | equality function ()

numpy.core.defchararray.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 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.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 ( `numpy` )

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

 
# check if they are equal

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

print ( "Output array:" , out_arr) 

 

Output :

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

Code # 2:

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

 
# numpy import

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) 

  
# check if they are equal

out_arr = geek.char.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: [False True False]
