This function can be util for transform pattern strings like these to list:

>>> pattern_to_list('42-45')
[42, 43, 44, 45]

>>> pattern_to_list('15,49-52')
[15, 49, 50, 51, 52]

>>> pattern_to_list('0-13')
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13]

            ret.append(int(e1.strip()))
        elif e1.strip().find('-') >= 0:
            s, e = e1.strip().split('-')
            ret += range(int(s.strip()), int(e.strip())+1)
