can a python tell whos its owner is?

[chetman7]

I said yes, I'm not 100% sure, the only thing I can tell is that at least with the bp, when I hold him he stretches out, comfortable, relaxed....if my roomate grabs him or something he stays balled up and it takes him a minute or two to really stretch out or anyhting

+1 mine does that too. In my care, he loves venturing off and exploring. but with anyone else, he is very cautious
