This is awkward. You can match directly on what you want:

In [7]: import re

In [8]: s = 'Association of British Travel Agents (ABTA) No.
56542\nAir Travel Organisation Licence (ATOL)\nAppointed Agents of
IATA (IATA)\nIncentive Travel & Meet. Association (ITMA)'

In [9]: licenses = re.split("\n+", s)

In [10]: licenseRe = re.compile(r'\(([A-Z]+)\)( No. (\d+))?')

In [11]: for license in licenses:
   ....:     m = licenseRe.search(license)
   ....:     print m.group(1, 3)

('ABTA', '56542')
('ATOL', None)
('IATA', None)
('ITMA', None)
