itertools can help you do this too:

import itertools
tl = [('0A',), ('1B',), ('2C',), ('3D',)]

itertools.chain.from_iterable(tl)
<itertools.chain object at 0x11f7ad0>

list(itertools.chain.from_iterable(tl))
['0A', '1B', '2C', '3D']


Checkout http://docs.python.org/library/itertools.html#itertools.chain
for more info.
