Here's a good function header given the following:
I wrote the below code

    output = {}
    cursor.execute('SHOW    GRANTS    FOR    %s@%s', (user, host))
    grants = cursor.fetchall()
    def pick(x):
        if (x == 'ALL    PRIVILEGES'):
            return 'ALL'
        else:
            return x
    for grant in grants:
        res = re.match("GRANT    (.+)    ON    (.+)    TO    '.*'@'.+'(    IDENTIFIED    BY    PASSWORD    '.+')?    ?(.*)", grant[0])
        if (res is None):
            raise InvalidPrivsError(('unable    to    parse    the    MySQL    grant    string:    %s' % grant[0]))
        privileges = res.group(1).split(',    ')
        privileges = [pick(x) for x in privileges]
        if ('WITH    GRANT    OPTION' in res.group(4)):
            privileges.append('GRANT')
        if ('REQUIRE    SSL' in res.group(4)):
            privileges.append('REQUIRESSL')
        db = res.group(2)
        output[db] = privileges
    return output

What's a good function header?
