I think your code is perfectly readable and clean, but you can flatten
it like so:
def get_tweets(term, get_page):
page_nums = itertools.count(1)
pages = itertools.imap(api.getSearch, page_nums)
valid_pages = itertools.takewhile(bool, pages)
tweets = itertools.chain.from_iterable(valid_pages)
return tweets
