Tanks and lights are hard to manage. I would look at putting the animal in a tub.

If the animal just ate a week ago, this is not an emergency situation and it should be fine. If you are going to own a ball python you are going to drive yourself nuts if you worry about them eating. There are a lot of threads on here about feeding issues full of good information. Worry about if the animal looks healthy or not. Post a picture if you are really concerned and we can let you know how the animal looks.
