numpy string operations | not_equal() function Last Updated : 28 Nov, 2022 Comments Improve Suggest changes Like Article Like Report 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.
