Addendum:
Since that snake will be in an open space... yes, it needs the appropriate sized hides. One on each end of its thermal gradient (hot - cool side).
Not using hides can be done, but as a new owner, and an owner that will not have his snake in a rack, or in a separate room... hides are imperative.
Jas is talking about advanced husbandry, something that you do not need to worry about right now. Your priority is to have an appropriate space set up so that when you bring your snake home he can settle in and be a snake.
It will give you a both a positive start and benefits snake and keeper.
