Jan Stránský proposed the following answer:
Hello,

modify the box's orientation.
The proper usage depends on your actual needs, like if it is to 45° or by 45° etc.
E.g. something like:
###
box = utils.box((1,1,1),(1,1,1))
# note using utils.box to prevent name clash
# note using box as a result of utils.box, not O.bodies.append
boxID = O.bodies.append(box) # here the result is ID (number)
axis = (0,0,1) # parallel to the z axis
angle = 0.25 * pi # 45 degrees
box.state.ori = axis, angle
# or more verbose
box.state.ori = Quaternion(axis, angle)
###

Cheers
Jan
