Ugh. I know using a listcomp was the point but I find using struct so
much more elegant.
>>> import struct
>>> data = 'AAABBBBBCCCCCCCCCDD'
>>> format = '3s5s9s2s'
>>> struct.unpack(format, data)
('AAA', 'BBBBB', 'CCCCCCCCC', 'DD')
Friends don't let friends abuse list comprehensions.
I made sure the code works this time :)
