How to use the pyclipper.Orientation function in pyclipper

def orient_path(path, dir):
    orient = pyclipper.Orientation(path)
    path = pyclipper.scale_to_clipper(path, SCALING_FACTOR)
    if orient != dir:
        path = pyclipper.ReversePath(path)
    path = pyclipper.scale_from_clipper(path, SCALING_FACTOR)
    return path
