Btw, if you are not familiar with pymel it's a 3rd party developed alternative to maya.cmds. It's much more pythonic and ships with Maya by default now. It basically wraps up the default maya python implementation plus the maya python API and defers to the faster implementation automatically. I'm sure it's much more elegant than that, but that's what it does in a nut shell :).
