Python: string to list with user defined splits

Question

I know that in Python there's the possibility of converting a given string into a list:

>>> h='ghilmnoPqzH'
>>> list(h)
['g', 'h', 'i', 'l', 'm', 'n', 'o', 'P', 'q', 'z', 'H']

But how can I split the list into given intervals? I.e., given the above string h if I set a parameter s=4 I should get

['ghi', 'lmn', 'oPq', 'zH']

This question is different from How do you split a list into evenly sized chunks in Python? because, if I use that function I get the following error:

<generator object chunks at 0x0296A030>

Not really. I have tried to apply that function and I get the error `` — james42, Dec 08 '15 at 11:06

>>> interval = 3
>>> s = 'ghilmnoPqzH'
>>> [s[start:start + interval] for start in range(0, len(s), interval)]
['ghi', 'lmn', 'oPq', 'zH']
