Manipulating Binary Data

[snippsat]

I want it to be [AA08+data, AA08+data]

You could probably join element before the goes in the list.
It had been better if you post sample code that we can run.
Can of course join element in a list that has been made.

>>> lst = ['AA08', 'data', 'AA08', 'data']
>>> it = iter(lst)
>>> [''.join(each) for each in zip(it, it)]
['AA08data', 'AA08data']
