Unless it's absolutely essential, leave it alone if it's wrapped around something. If it's moving around, or coiled up, confidently but not too quickly move your hand to grab it. As a newbie, you might get the occasional strike out telling you to leave it alone. You need to be able to judge when you can pick up your snake, and the occasional lash out strike is worth it in the learning process. If it always lashes out, or tries to run away, pick it up anyway. It should calm down once out of the tank.
Hope this helps.
