I think what you want is numpy.roll?
Definition: numpy.roll(a, shift, axis=None)
Docstring:
Roll the elements in the array by 'shift' positions along
the given axis.
>>> from numpy import roll
>>> arange(10)
array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9])
>>> roll(arange(10), 2)
array([8, 9, 0, 1, 2, 3, 4, 5, 6, 7])
