I am ecstatic about the idea of getting n items at a time from a
generator! This would eliminate the use of less elegant functions to do
this sort of thing which I would do even more frequently if it were
easier.
Is it possible that this syntax for generator expressions could be adopted?
>>> sentence = 'this is a senTence WiTH'
>>> generator = (word.capitalize() for word in sentence.split())
>>> print generator.next(3,'PadValue')
('This','Is','A')
>>> print generator.next(3,'PadValue')
('Sentence','With','PadValue')
>>> generator.next(3,'PadValue')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
StopIteration

While on the topic of generators:
Something else I have longed for is assignment within a while loop. (I
realize this might be more controversial and might have been avoided on
purpose, but I wasn't around for that discussion.)
>>> sentence = 'this is a senTence WiTH'
>>> generator = (word.capitalize() for word in sentence.split())
>>> while a,b,c = generator.next(3,'PadValue'):
... print a,b,c
...
This Is A
Sentence With PadValue
