In the wild, most snakes, especially boids, are sporadic feeders. They often don't eat for a week or so before finding a good prey item and gorging themselves. Humans are different because our food is easier to find. Lizards are similar to humans because they can run around all day eating crickets, thus having a continuous source of energy, while your python is a top predator, and a cold-blooded one at that. Alligators, sharks, and Gila monsters are similar because their prey is harder to obtain; thus it is more convenient to be able to eat a lot at one sitting and wait a long time before eating again, rather than having to ambush small prey items every day.
That being said, don't let your snake eat as much as it can all at once, because it will. Obviously for your python food is not at all hard to find when it is offered, but keep in mind that the snake's metabolism is adapted to being in the wild, not in captivity where it is fed on a consistent basis. In short, I wouldn't worry too much about the feeding schedule within a week, so long as your snake eats and seems comfortable.
