Sample

# use prefix PyRxCmd_ to define a command called doit1
def PyRxCmd_doit1():
    try:
        db = Db.curDb()
        filter = [(Db.DxfCode.kDxfStart, "LINE")]
        ps, ss = Ed.Editor.select(filter)
        if ps != Ed.PromptStatus.eOk:
            return

        lines = [Db.Line(id) for id in ss.objectIds()]
        for line in lines:
            print(line.startPoint().distanceTo(line.endPoint()))

    except Exception as err:
        traceback.print_exception(err)

# or use decorator to define a command called doit2
@Ap.Command("doit2", Ap.CmdFlags.kMODAL)
def function_setlayer():
    try:
        db = Db.curDb()
        ps, id, _ = Ed.Editor.entSel("\nSelect a line: ", Db.Line.desc())
        if ps != Ed.PromptStatus.eOk:
            return

        # all DbObjects accept an ID in the constructor
        # line is garbage collected and closed
        line = Db.Line(id, Db.OpenMode.kForWrite)
        line.setLayer("0")

    except Exception as err:
        traceback.print_exception(err)
