I can't get points coordinates after I divide the circle by 6 points by 'DivedeCurve'

Dear all,
I am learning …
I met a problem after I divide a circle by 6 points when the circle is generated by picking a point in rhino and AddCircle.
After many rounds of coordinating with Chatjpt, I still got faulty feedback.
The script is below:

import rhinoscriptsyntax as rs
point = rs.GetObject ('select the center point',rs.filter.point)
point_coord = rs.PointCoordinates(point)
radius = rs.GetReal ("radius of new circle", 3.14, 1.0)
if radius:
    curve = rs.AddCircle( (point_coord), radius )

points = rs.DivideCurve(curve, 6, True, True)
for point in points:
    point_coord = rs.PointCoordinates(point)

the feedback is

Message: Parameter must be a Guid or string representing a Guid

  line 890, in coerceguid, "C:\Users\Lenovo\AppData\Roaming\McNeel\Rhinoceros\7.0\Plug-ins\IronPython (814d908a-e25c-493d-97e9-ee3861957f49)\settings\lib\rhinoscript\utility.py"

I assume the divideCurve command causes this problem, but as a newbie, I haven’t figured out the correct way…
If someone can help, that will be an excellent thanks from me!!


There’s the problem.

Scrap this, go back to a tutorial for the package you’re trying to use, and start over.
