I've not read all of it, and it overlaps a fair bit with Learning Python, but the free Dive Into Python reads well and is often cited as a good intro for those with programming experience. <http://diveintopython.org/>. It is also available as a dead-tree product from APress.
I found Dive Into Python to be very useful when I got my hands wet with Python. It's a great read by a funny author, very much recommended.
