Grapple
As a standard action, you can attempt to grapple a foe, hindering his combat options.(Combat - Pathfinder_OGC)
When Grappling, Grappler must try to grab foe's head, limbs or body .
whatever the Grappler grab, foe's action must be limited even attack.
In reality, it's hard to imagine that human can full-attack the python when python is Grappling the human
The other question (not seriously)

Constrictor snake can kill crocodile by constrict easily. but lion can't kill crocodile by bite even it has pounce
