This can be simplified with a fillvalue
>>> s = "abracadabra"
>>> for chunk in itertools.zip_longest(*[iter(s)]*4, fillvalue=""):
... print("".join(chunk))
...
abra
cada
bra
but for sequences I prefer regular slicing:
>>> N = 4
>>> for start in range(0, len(s), N):
... print(s[start:start+N])
...
abra
cada
bra
