If you insist on one-liners, it can be done without sum(), though it
probably doesn't buy you much in readability:

from itertools import chain
[list(chain(*row)) for row in foo]

By the way, if this was not a toy example and you're doing serious work
with n-dimensional arrays, make yourself a favor and install NumPy;
it's usually both faster and more elegant for array manipulations than
pure python.
