carpets and bloods for beginners.
My Irian Jaya was actually the most aggressive snake I have ever owned. Most people are surprised to hear that, but from the first time I picked it up at the airport to the last time he nailed me in the eye the guy was always in attack mode. I believe most carpets are pretty restless, not necesarily aggressive. You can tame them to the point where they don't bite but most Jungles, Irian Jayas, and Coastals I know of won't sit still for anything. They are constantly on the move and often don't tolerate a lot of unnecesary handling. So while they may not always be biters, they are typically (again, not all) energetic and fast moving pythons.
I also wouldn't recommend a blood python, like one of the previous posters suggested. I don't doubt that they have a nice one and they are, indeed, gorgeous animals to look at, but they are typically not the calmest pythons on the market. I have seen tame ones. But again, that isn't the norm, especially with all the imported ones being offered so cheap.
