numpy string operations | equal() function (original) (raw)

Last Updated : 26 Jan, 2019

numpy.core.defchararray.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 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.

Python program explaining

numpy.char.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 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

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 equal

out_arr = geek.char.equal(in_arr1, in_arr2) print ("Output array: ", out_arr)
