Photo periods don't mean anything when it comes to snakes eating, snakes depend on temps to tell them what time of year it is.
None of my snakes get a photo period, some have reflector spot lights (1 per cage) others have blue lights or kept in unlit draws, they do get light through a window but this doen't provide enough light to overcome the light globes. Lights are run on a thermostat and turn on and off all day and night, my snakes feed and breed well. IMO photo periods are not required for pythons.

Double check your air temps and make sure it can hide somewhere warm and just be patient, if it's fed in the past it will feed for you.
Also make sure it has access to water.
