how to tell if a ball python is relaxed?

[Gc99]

What indicators/ body language is there to tell if your BP is relaxed? Or not relaxed?

Obviously there's the striking pose, and then I saw in a video if you rub your finger along the body and the body moves away, then they're relaxed (based on the premise that they puff full of air to look bigger when scared).

Is there anything else? Does moving faster than normal, not flicking tongue, that kind of stuff give any information?

In the enclosure I've heard that moving around during the day is a sign of a stress, is just lying around also a sign?

cheers

Also, moving around during the day means they are hungry or that they pooped inside their hide, at least both my snakes do that lol
