PLEASE get a thermometer asap. Ball pythons are not the easiest snakes to keep, but if you do your research, they can be good beginner snakes. It is very important that the temperatures (warm side and cool side) and the humidity in the tank are just right if you want your snake to be healthy and happy.
As someone already said, wait at least a week before you try to hold him. But personally, I would go beyond that. I would wait a week (or maybe even two weeks depending on how long you can stand to wait) and then attempt to feed him. Ball pythons can be picky eaters and if they are under any stress some balls can tend not to eat. If a ball python is stressed out, handling him can make it even worse. So if he eats on the first attempt, give him a few days to digest, and then if you want you can try to handle him. I would start off slow. Handle him once a week for no more than 15 minutes. Then as you become more comfortable with him and vise versa, and if he continues to eat for you, you can gradually start handling him more. If he doesn't eat, leave him alone for a little longer.
Okay, now I've rambled too. I would also like to know what that is you are using for bedding, and how you are heating the tank. How many hides do you have? Make sure you have 2 hide spots for your snake, one on the warm side, and one on the cool side, and of course, a water bowl.
And do your research! Read the caresheets on this website. I'd suggest picking up The Ball Python Manual, you can find it at any pet store. And this website is a great resource, ask lots of questions. Welcome to the site!
