Overwriting Layer

Hi everybody,
I'm not an expert in programming with python and I would like to know the procedure to overwriting a layer with some lines, after I run again the script. Otherwise, every time I will modify the reference surfaces I will have always new lines.

Thank you
Ale

This is my script for now:

import rhinoscriptsyntax as rs
import Rhino.Geometry as rg

surface_base = rs.GetObject('Select the base surface')
surface_top = rs.GetObject('Select the top surface')
points1 = rs.SurfaceEditPoints(surface_base)
points2 = rs.SurfaceEditPoints(surface_top)

for point in points1:
    base_points = rs.AddPoints(points1)
    for point in points2:
        top_points = rs.AddPoints(points2)
    
for point1 in points1:
    for point2 in points2:
        lines = rs.AddLine(point1,point2)
        rs.ObjectLayer(lines,'dummy')
