Robert Caulk proposed the following answer:
Hello,

state.disp() is a vector [1] representing the current position -
reference position.

You probably want the magnitude of the displacement:

import numpy.linalg as la
tDispl = la.norm(O.bodies[1].state.displ())

or maybe you are only interested in one of the components:

tDispl = O.bodies[1].state.displ()[0]

Best,

Robert
