That is not common for a ball python to be that ok with being toted around. Most ball pythons, in my opinion are not going to be ok with being handled constantly. If you are really dead set on getting a ball python, go ahead, but I'm just fore-warning you that these things can give you problems down the road. Why take the chance? Just do some research and find a breed that is more tolerant of those things and fits your ideas better? I have a corn snake, she's my baby. I have her because I wanted a snake that I could hold all the time. She's tame as a puppy, and I can even touch her head and she doesn't mind. Much different than my head-shy BP. She would be out all day if I'd let her, and she would definitely enjoy having a large enclosure to roam around in.
I really would consider a corn, but I heard they're not one to chill around your neck. I have dogs, so I can't have it escaping. I heard Ball Python's are much slower, and lazy.
