That doesn't necessarily work:

import itertools

x = (1, 2, [3, 4, (5, 6)])
y = ([1, 2, (3, 4)], 5, 6)
z = (1, [2, 3, (4, 5)], 6)

def flatten(listOfLists):
    return list(itertools.chain(*listOfLists))

print flatten(x)
print flatten(y)
print flatten(z)

==> TypeError: chain argument #1 must support iteration
