Welcome to the world of ball pythons lol. Check your husbandry and make sure that everything is spot on, sometimes issues with temp/humidity will cause them to not eat. Also make sure that your enclosure has at least two hides, one on the warm side and one on the cool side since all pythons are nocturnal animals that spend the day in rodent burrows they need places to hide and feel secure, being insecure can also cause them to go fast. If Coco is in an aquarium make sure that the back and sides of the aquarium are covered to also help her feel more secure. My boy refused to eat for about a month after I got him, sometimes they just need a chance to get used to their new environment so it is best to give them a week or so to adjust before handling them (very hard I know, I barely made it lol). Be patient and consistent it is completely normal for them to go off of food for a period of time. Just keep track of her weight and make sure she is not losing to much. Also make sure there are no health related reasons for her to refuse food (parasites, RI, etc). Also they can refuse food when going into shed.

How old is she?
What are you feeding?
How often are you trying to feed?
Do you move her to a different tank to feed?
How big is your enclosure, how many hides?
