Do you mean carpet python?
How old is she? Because it's not uncommon for hatchies to be snappy, they normally tend to grow out of it (however some sankes just don't like to be touched at all, more of a look at than handle snake) You should leave her alone for 1 - 2 weeks so she can settle down into her new environment, don't disturb her, unless you're changing her water. Also what is she housed in? A click clack or an enclosure? Is the enclosure/click clack placed in a low traffice room?
I've read on here that if you get a rag and whipe some of your sweat on it and then place it in the snakes enclosure/click clack and then leave it there over a period of time, the snake associates that scent as a save place, that might be something to think about.
Once you are confident that she has settled down, handle her 2 or 3 times a week, for no more than 10 minutes each time, you don't want to stress her out.
