def split_on_zero(data):
    start = 0
    for (i, n) in enumerate(data):
        if n == 0:
            yield data[start:i]
            start = i + 1
    yield data[start:]

>>> list(split_on_zero([3, 7, 4, 0, 1, 3, 7]))
[[3, 7, 4], [1, 3, 7]]
>>> list(split_on_zero([0, 1, 2, 0, 3, 4, 5, 0]))
[[], [1, 2], [3, 4, 5], []]
