Joining every four strings in a list

Question

I have a list like this:

['Ww','Aa','Bb','Cc','ww','AA','BB','CC']

And continuing in such a pattern, with varying capitals and lowercases. What I want to do is join every four items in this list together. So, the resulting new list (given the one above) would look like this:

['WwAaBbCc', "wwAABBCC']

How would I go about this?

Answer 1

>>> L = ['Ww','Aa','Bb','Cc','ww','AA','BB','CC']
>>> [''.join(x) for x in zip(*[iter(L)] * 4)]
['WwAaBbCc', 'wwAABBCC']

Answer 2

my_list = ['Ww','Aa','Bb','Cc','ww','AA','BB','CC']
[''.join(my_list[i:i + 4]) for i in range(0, len(my_list), 4)]

Answer 3

You can use something like this:

def _get_chunks(lVals, size):
    for i in range(0, len(lVals), size):
        yield lVals[i: i + size]

data = ['Ww','Aa','Bb','Cc','ww','AA','BB','CC']


output = [''.join(chunk) for chunk in _get_chunks(data, 4)]
>>> ['WwAaBbCc', 'wwAABBCC']
