Here are some various 'functional' solutions. Pick the one that fits
your problem best:

result_list = [fn for fn,ln in tuple_list]

result_generator = (fn for fn,ln in tuple_list)

result_list = map(lambda (fn,ln): fn, result_list)

result_generator = itertools.imap(lambda (fn,ln): fn, result_list)
