Tips for taming male blood?

[Will0W783]

Hi guys,
I just bought a pair of Sumatran Red Blood pythons at a reptile show on Saturday. The female is a sweetheart. The male was docile at the show, but once I got him home he has become irascible. He was trying to attack my camera when I went to take his picture, and he strikes at me when I pick him up, albeit not very well. His aim sucks so it is rather pitiful when he tries to bite me. But the guy who sold him to be said he was "cool", so I'm hoping I can calm him down. These are my first bloods, and I know they tend to be nippy, so if anyone with experience handtaming them has any suggestions or tips for me I'd really appreciate it.
