numpy string operations | rsplit() function

numpy.core.defchararray.rsplit(arr, sep=None, maxsplit=None) is another function for doing string operations in numpy. It returns a list of the words in the string, using sep as the delimiter string for each element in arr. The rsplit() method splits every string array element into a list, starting from the right whereas the split() method splits every string array element into a list, starting from the left.

Parameters:
arr : array_like of str or unicode.Input array.
sep : [ str or unicode, optional] specifies the separator to use when splitting the string.
maxsplit : [ int, optional] how many maximum splits to do.

Returns : [ndarray] Output Array containing of list objects.
