Hi,

I think you are looking for itertools.chain, or in this case, 
itertools.chain.from_iterable:

In [1]: x = [['A0','A1','A2'], ['B0','B1','B2'], ['C0','C1','C2']]

In [2]: import itertools

In [3]: [ y for y in itertools.chain.from_iterable(x)]
Out[3]: ['A0', 'A1', 'A2', 'B0', 'B1', 'B2', 'C0', 'C1', 'C2']

HTH
