Thanks for the comments, I get licks occassionally. These are breeder rats but I treat them like as kindly as I'd treat a pet. My girl Dumbo (the dumbo rat lol) is my only pet and she is really sweet.

I've had rats as pets for more years than I care to admit and I've never had a true bite from one. My bp's have bitten me worse than any of my rats every have.
You're lucky! I had a mean weanling guy I bought as a feeder rat bite one of my finger tips once and he didn't let go until I pulled him off (he had held on for about 5 seconds, and kept flexing his jaws). I had a bit nerve damage for a few weeks in that finger tip, it tingled for a while whenever I touched something around the bite spot. I think I'm lucky it didn't get infected, the deepest wound was almost to the bone.

An adult ball python feeding bite is nothing compared to even a small rat bite. Which is why I'm a bit intimidated by my rats lol
