I'd like you to write a function that accepts a sequence and a number n and returns one list-of-lists containing lists of size n.

It should work something like this:

>>> for chunk in chunked([1, 2, 3, 4, 5], n=2):
...     print(*chunk)
...
1 2
3 4
5
>>> for chunk in chunked(range(10), 4):
...     print(tuple(chunk))
...
(0, 1, 2, 3)
(4, 5, 6, 7)
(8, 9)

Try to solve this exercise without using any third-party libraries (without using more-itertools or boltons for example).

Before attempting any bonuses, I'd like you to put some effort into figuring out the clearest and most idiomatic way to solve this problem.
