Okay first things first, Chuck. You need to think like a snake here. This snake is fairly young. She's just come into your home recently, a home with new smells, new routines, new vibrations, etc. She doesn't have the mental capacity to understand these changes. She's a creature driven by instincts and the greatest of those is simply to survive. Part of that survival instinct is also to feed but if she's stressed, she'll pass on that for now.

Handling stresses these snakes. They aren't domesticated or tame pets even if they are hatched in captivity from captive snakes. They can get used to us and learn to tolerate our handling but I truly don't believe they can ever be like our pet dog or cat in that they seek or want handling from us. Think of handling like a gift the snake allows you. For now that gift isn't one you should be seeking from this young, stressed non-eater.

Focus on the basics. Make sure your enclosure is correct and appropriate for a ball python of this age/size. Make sure the room you keep this snake in is quiet and has low traffic. Do not handle the snake or bother it unduly. Don't allow others to constantly bug at the snake or it's enclosure. Don't constantly push food at it. Allow this shy, young snake to start to feel at home in it's new home. Basically leave it be and let it settle in for the next 5 days or so (that's dependent of course on whether she's currently set up properly).

To help you more it would be helpful to know more about this snake and it's home and your routines.

Where did you get this snake from?
How long have you had this snake?
Describe in detail the housing this snake lives in (size, substrate, hides provided, heating source, temps and humidity and how you measure those as well as where the enclosure is located in your home - pictures help here).
What have you tried to feed and how often?
What information do you have about this snakes routines prior to you purchasing it? (things like when it fed, what it ate, how often it ate, etc.)

Refusing to eat, Chuck, isn't a problem. It's a symptom or a sign of a problem or set of problems. Let's try to figure out what those problems are and hopefully get your snake eating and you feeling a bit better about the situation.
