This MAY be true for other species, but I'm certain it's not for a Ball Python.
They can't wrap thier tails around anything really, being so short and stubby, and they sure don't inhabate trees in thier lives in the wild.
The only place you will find a ball python in the wild is in a burrow, or if it's hunting at night, on the ground.
Never once heard of a Ball Python living in trees. They may use trees and branches in captivity that are placed in the enclosure, but thats merely just a way to try to get out. Using the limb as a tool of hieght.
