Consecutive, Overlapping Subsets of Array (NumPy, Python)

Question

I have a NumPy array [1,2,3,4,5,6,7,8,9,10,11,12,13,14] and want to have an array structured like [[1,2,3,4], [2,3,4,5], [3,4,5,6], ..., [11,12,13,14]]

Answer 1

Quick&dirty solution:

>>> a = numpy.arange(1,15)
>>> numpy.array([ a[i:i+4] for i in range(len(a)-3) ])
array([[ 1,  2,  3,  4],
       [ 2,  3,  4,  5],
       [ 3,  4,  5,  6],
       [ 4,  5,  6,  7],
       [ 5,  6,  7,  8],
       [ 6,  7,  8,  9],
       [ 7,  8,  9, 10],
       [ 8,  9, 10, 11],
       [ 9, 10, 11, 12],
       [10, 11, 12, 13],
       [11, 12, 13, 14]])
