Use a generator and have it /yield/ rather than /return/ results:

>>> def f(items):
...     for item in items:
...             yield item.isdigit(), item.isupper()
... 
>>> for result in f("AAA bbb 111".split()):
...     print result
... 
(False, True)
(False, False)
(True, False)

This is a very memory-efficient approach, particularly if the input items
are created on the fly, e. g. read from a file one at a time.
