take a look here: https://developer.rhino3d.com/api/RhinoScriptSyntax/
many rhino common functionalities are already wrapped inside the script syntax. look below for an example on how to select many objects with filter.

import rhinoscriptsyntax as rs

objs = rs.GetObjects("Get Points", 1+2)

should give you a list of points or point sets.

Hi @15951991225,

How about this?

import Rhino

def test_joann():
    filter = Rhino.DocObjects.ObjectType.Point | Rhino.DocObjects.ObjectType.PointSet
    go = Rhino.Input.Custom.GetObject()
    go.GeometryFilter = filter
    go.GetMultiple(1, 0)
    if go.CommandResult() != Rhino.Commands.Result.Success:
        return False
    
    count = 0
    for objref in go.Objects():
        geometry = objref.Geometry()
        if isinstance(geometry, Rhino.Geometry.Point):
            count += 1
        elif isinstance(geometry, Rhino.Geometry.PointCloud):
            count += geometry.Count
    
    print("Total points: {}".format(count))
    return True
    
test_joann()

but I do not know how to assign the coordinates of the pointcloud

Can you give me some advice? Thank you!

You should use Pointcloud.Getpoints first and the iterate over the points.
