No.
$ python -m timeit -n20000 -s"items = []" "items.append(42)"
20000 loops, best of 3: 0.554 usec per loop
$ python -m timeit -n20000 -s"items = [42]*10**6" "items.append(42)"
20000 loops, best of 3: 0.529 usec per loop

Peter,
So its actually faster to append to a long list than an empty one? That
certainly would not have been intuitively obvious now would it?
