I agree with the others. Always wash your hands before handling, and keep some vinegar or listerine close by if he bites. In time and with patience and consistent gentle handling he should calm down. I'd start with short handling sessions of 5-10 minutes every couple of days and increase the time and frequency until he calms down. If he doesn't calm down then hopefully he'll make a nice display animal. I hope he's not just a mean snake. Best wishes.
