I've run into the necessity of implementing chunks() again. Here is the code I've made from scratch.
def chunks(seq, size): '''Cut sequence into chunks of given size. If `seq` length is not divisible by `size` without reminder, last chunk will have length less than size.
>>> list( chunks([1,2,3,4,5,6,7], 3) ) [[1, 2, 3], [4, 5, 6], ] ''' endlen = len(seq)//size for i in range(endlen): yield [seq[i*size+n] for n in range(size)] if len(seq) % size: yield seq[endlen*size:]

Now that Python 3 is all about iterators (which is a user killer feature for Python according to StackOverflow - http://stackoverflow.com/questions/tagged/python) would it be nice to introduce more first class functions to work with them? One function to be exact to split string into chunks.
itertools.chunks(iterable, size, fill=None)
Which is the 33th most voted Python question on SO -

Anatoly, so far there were no negative votes -- would you care to go another step and propose a patch?
