Rubik's cube translation

How do I get a Rubik's cube translation out of this:

a= numpy.array([[0,1,2],[3,4,5],[6,7,8]])
a
array([[0, 1, 2],
[3, 4, 5],
[6, 7, 8]])
a[:,0],a[:,1],a[:,2] #no good
(array([0, 3, 6]), array([1, 4, 7]), array([2, 5, 8]))


I need [[ 6, 3, 0 ], [ 7, 4, 1 ], [ 8, 5, 2 ]].

c= numpy.array([[ 6, 3, 0 ], [ 7, 4, 1 ], [ 8, 5, 2 ]])
c
array([[6, 3, 0],
[7, 4, 1],
[8, 5, 2]])
.
