How a python kills its prey does it need to break its bones while it kills its prey?

Pythons swallow there prey whole without spitting anything, out including bones. This also means they would have a strong digestive system, so they wouldn't need to break the prey's bones first - they will be broken up inside it's stomach. Snakes also have a very slow digestive system, that is why they don't feed again for weeks or months at a time.
