Ball pythons are nocturnal. I have noticed mine tends to come out (sometimes) at 10pm or so and usually returns to her hide by 1am. Is your red light a nocturnal bulb? Also ballpythons are not very active. Mine sleeps 90% of the time. If she is new she needs time to adjust. If you wear a shirt all day (don't add perfumes or anything) and put it into her enclosure you can help her become more familiar with your smell.
