A week of settling in time is generally recommended. The most important part is to be sure you are providing a stress free environment. Make sure your temps & humidity are spot-on BEFORE you bring home the snake. And, hard as it is, avoid handling except the minimum required for cage maintenance until your BP has established a good eating routine in her new home.
