# Rubik's cube translation

 P: n/a 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]]) Mar 31 '08 #1

If you don't want changes to D to affect E, then you need to disconnect them when you create them. If you create D and E so that they contain references to the same lists, then this kind of thing will happen. -- Tim Roberts, ti**@probo.com Providenza & Boekelheide, Inc. Apr 1 '08 #4

If you don't want changes to D to affect E, then you need to disconnect them when you create them. *If you create D and E so that they contain references to the same lists, then this kind of thing will happen. Basically, I need to change both D row 3 and E row 1 at the same time. Apr 1 '08 #5
