Python code does not work correctly!

Hi
I am trying to run the following code in PythonScript:
Source: https://developer.rhino3d.com/samples/rhinocommon/add-radial-dimension/

from Rhino import *
from Rhino.DocObjects import *
from Rhino.Commands import *
from Rhino.Geometry import *
from Rhino.Input import *
from scriptcontext import doc

def RunCommand():
rc, obj_ref = RhinoGet.GetOneObject(“Select curve for radius dimension”, True, ObjectType.Curve)
if rc != Result.Success:
return rc
curve, curve_parameter = obj_ref.CurveParameter()
if curve == None:
return Result.Failure

if curve.IsLinear() or curve.IsPolyline():
    print "Curve must be non-linear."
    return Result.Nothing

# in this example just deal with planar curves
if not curve.IsPlanar():
    print "Curve must be planar."
    return Result.Nothing

point_on_curve = curve.PointAt(curve_parameter)
curvature_vector = curve.CurvatureAt(curve_parameter)
len = curvature_vector.Length
if len < RhinoMath.SqrtEpsilon:
    print "Curve is almost linear and therefore has no curvature."
    return Result.Nothing

center = point_on_curve + (curvature_vector/(len*len))
_, plane = curve.TryGetPlane()
radial_dimension = RadialDimension(center, point_on_curve, plane.XAxis, plane.Normal, 5.0)
doc.Objects.AddRadialDimension(radial_dimension)
doc.Views.Redraw()
return Result.Success

if name==“main”:
RunCommand()

Prompt error, because RadialDimension() does not require parameters!
Hint: “Message: RadialDimension() takes no arguments (5 given)”
Is it wrong? How to correct?

thanks!
