From my experience, that do not really make any difference when you take them out or so. I would not take her for more than 30 minutes / week. But if it's the first time, don't take it out for more than 5 minutes, don't stress it ! go gradually. Oh and if she try to bite you, let her do. It's better when they are young. IF they bite and you do not react or feel affraid, they will believe it's useless to bite, so they will tame in the future.

Truelly, I do not think it's good to take out a snake. Well, I do it, but they do not really like it. So most of the time, I only take my snake out when I am cleaning their cage. I have them around my neck or something like that and put them back in after.
