Split a string to even sized chunks

Question

How would I be able to take a string like \'aaaaaaaaaaaaaaaaaaaaaaa\' and split it into 4 length tuples like (aaaa,aaaa,aaaa

Answer 1

Using list comprehension, generator expression:

>>> s = 'aaaaaaaaaaaaaaaaaaaaaaa'
>>> [s[i:i+4] for i in range(0, len(s), 4)]
['aaaa', 'aaaa', 'aaaa', 'aaaa', 'aaaa', 'aaa']

>>> tuple(s[i:i+4] for i in range(0, len(s), 4))
('aaaa', 'aaaa', 'aaaa', 'aaaa', 'aaaa', 'aaa')

>>> s = 'a bcdefghi j'
>>> tuple(s[i:i+4] for i in range(0, len(s), 4))
('a bc', 'defg', 'hi j')
