[Tutor] using re to build dictionary

[Norman Khine]

Hello,
 From my previous post on create dictionary from csv, i have broken the 
problem further and wanted the lists feedback if it could be done better:

 >>> s = 'Association of British Travel Agents (ABTA) No. 56542\nAir 
Travel Organisation Licence (ATOL)\nAppointed Agents of IATA 
(IATA)\nIncentive Travel & Meet. Association (ITMA)'
 >>> licences = re.split("\n+", s)
 >>> licence_list = [re.split("\((\w+)\)", licence) for licence in licences]
 >>> association = []
 >>> for x in licence_list:
...     for y in x:
...         if y.isupper():
...            association.append(y)
...
 >>> association
['ABTA', 'ATOL', 'IATA', 'ITMA']


In my string 's', I have 'No. 56542', how would I extract the '56542' 
and map it against the 'ABTA' so that I can have a dictionary for example:

 >>> my_dictionary = {'ABTA': '56542', 'ATOL': '', 'IATA': '', 'ITMA': ''}
 >>>


Here is what I have so far:

 >>> my_dictionary = {}

 >>> for x in licence_list:
...     for y in x:
...             if y.isupper():
...                     my_dictionary[y] = y
...
 >>> my_dictionary
{'ABTA': 'ABTA', 'IATA': 'IATA', 'ITMA': 'ITMA', 'ATOL': 'ATOL'}

This is wrong as the values should be the 'decimal' i.e. 56542 that is 
in the licence_list.

here is where I miss the point as in my licence_list, not all items have 
a code, all but one are empty, for my usecase, I still need to create 
the dictionary so that it is in the form:

 >>> my_dictionary = {'ABTA': '56542', 'ATOL': '', 'IATA': '', 'ITMA': ''}

Any advise much appreciated.
