Don't worry. They can go a very long time without food. My two year old male just ate about a week ago after eight months off feed. He was a fantastic feeder before his fast. My advice is don't change anything. Offer him the same food, keep his temps the same, and keep his cage setup the same. Ball Pythons don't like change. One thing that sparks my Ball Pythons appetite is crunching the rat's bag and he pokes his head out, ready to eat. He learned that the sound means food. Just take care of him like you would normally and offer him a rat every couple of weeks.
