Thank you for your reply Neil.
I had seen that post in the ArcPy Café page already. I think that is meant for 10.1
It doesn't work for 10.0
The reason I need to shift 360 is to make the world "wider" (see image of the feature layer to be shifted East; in fact I need to shift one part +360 (East) and another -360 (West)) as a previous step to run Euclidean Distance so I can get a continuous raster layer instead of having a sharp end where both edges meat. The result is then clipped to the appropriate extent.
As I said, it is easy enough to use the Move functionality within an edit session but I need to include this process as a part of a larger python script.

In the image, the Feature layer in red needs to be shifted 360 East and the feature layer in blue 360 West
