I have an older Woma python male, several years old, and he has never bitten me. In fact it's usually hard to get him to eat most times. Now with my reticulated python she is a bit intimidating, if she bites me I'd probably need stitches LOL. Although she has never intentionally tried to bite me I almost got tagged a few times opening up her tub when she comes flying out from that food response. Now I always use a snake hook to gently rub her a bit before I pick her up and keep the hook between her head and my hand when I first go in to pick her up. Usually once a snake is picked up they are fine. If not, it's usually a juvenile thing they grow out of. Gloves and long sleeves help too, but my retic often has her head on my bare skin and that still kind of freaks me out, even though she has never bit me, the damage could be severe and you have to respect a snake like that. I actually used to be pretty scared of my Woma until I got my retic, she makes my Woma look like a little worm LOL.
