How to turn a tuple of lists into a list?

I am using Python 2.7 to turn a tuple of lists (of 2 elements) of float into a list of floats (([1.0],[2.0]) => [1.0,2.0]) like the following:

[tuple_lists[0][0],tuple_lists[1][0]]

Is there a pythonic 2.7 way to do so in a more elegant way?

>Solution :

[l[0] for l in tuple_lists]

l iterates over the lists in tuple_lists, each list having a single element.
