Just group your re:

    >>> import re
    >>> re.split("ab", "abracadabra")
    ['', 'racad', 'ra']
    >>> re.split("(ab)", "abracadabra")
    ['', 'ab', 'racad', 'ab', 'ra']

and you get it in the return value.  In fact, re.split with a grouped re is
very much like Raymond's str.partition method without the guarantee of
returning a three-element list.
