split a generator/iterable every n items in python (splitEvery)

Question

I\'m trying to write the Haskel function \'splitEvery\' in Python. Here is it\'s definition:

splitEvery :: Int -> [e] -> [[e]]
    @\'splitEvery\' n@ s         


        

Answer 1

This is an answer that works for both list and generator:

from itertools import count, groupby
def split_every(size, iterable):
    c = count()
    for k, g in groupby(iterable, lambda x: next(c)//size):
        yield list(g) # or yield g if you want to output a generator
