numpy.moveaxis(a, source, destination)
Move axes of an array to new positions.
Other axes remain in their original order.
Parameters:anp.ndarrayThe array whose axes should be reordered.
sourceint or sequence of intOriginal positions of the axes to move. These must be unique.
destinationint or sequence of intDestination positions for each of the original axes. These must also be unique.
Returns:resultnp.ndarrayArray with moved axes. This array is a view of the input array.

Examples
>>> importnumpyasnp>>> x=np.zeros((3,4,5))>>> np.moveaxis(x,0,-1).shape(4, 5, 3)>>> np.moveaxis(x,-1,0).shape(5, 3, 4)These all achieve the same result:
>>> np.transpose(x).shape(5, 4, 3)>>> np.swapaxes(x,0,-1).shape(5, 4, 3)>>> np.moveaxis(x,[0,1],[-1,-2]).shape(5, 4, 3)>>> np.moveaxis(x,[0,1,2],[-1,-2,-3]).shape(5, 4, 3)
