python - Find all consecutive sub-sequences of length n in a sequence

I want to find all consecutive sub-sequences of length n in a sequence.

E.g. say n was 3 and the sequence was:

[0,1,7,3,4,5,10]

I want a function that would produce as output:

[[0,1,7],[1,7,3],[7,3,4],[3,4,5],[4,5,10]]

Thanks in advance!

>>> x = [0,1,7,3,4,5,10]
>>> n = 3
>>> zip(*(x[i:] for i in range(n)))
[(0, 1, 7), (1, 7, 3), (7, 3, 4), (3, 4, 5), (4, 5, 10)]

If you want the result to be a list of lists instead of list of tuples, use map(list, zip(...)).
