I'm starting to fool around with ArcPy, and eventually want/need to migrate over our automated map atlases from VBA to ArcPy. One of my "old" functions that I need to carry over is to dynamically change the Page Size. This involves changing the data frame size and also the Page/Print size (File-->Page and Print Setup). I've found it quite easy to access the data frame properties via ArcPy, but cannot see how to change the Map Page Size using ArcPy. Can anyone point me in the right direction?
