numpy.core.defchararray.greater(arr1, arr2) is another function for doing string operations in numpy. It checks the elements of two same shaped string array one by one and returns True if the elements of arr1 greater than the elements of arr2 i.e. arr1 > arr2 .Otherwise, it returns False.
Parameters:
- arr1 : array_like of str or unicode.1st input array.
- arr2 : array_like of str or unicode.2nd input array.
Return Type : [ndarray] Output array of bools, or a single bool if arr1 and arr2 are scalars.
