How can we a create 2 named selections of bodies with and without el. resistivity defined?

Say we have some bodies that use material properties that do not have an electrical resistivity, and some that has this property defined (in engineering data). Can we via mechanical scripting create a named selection for all the bodes that have it and one for bodies that do not have any electrical resistivity defined?

Below is one way of doing this:

import materials
Idsthel = []
Idsth = []
with Transaction():
    bodies = ExtAPI.DataModel.Project.Model.GetChildren(DataModelObjectCategory.Body,True) # create list with all bodies in the Mechanical tree
    for body in bodies: #  loop on all bodies in Mechanical Tree
        #print(body.Name) #  print body name
        geo_body = body.GetGeoBody() #  get GeoData of this current body
        material = geo_body.Material #  access material class for this geo body
        #print(materials.GetListMaterialProperties(material)) #  print material properties defined for this body
        properties = materials.GetMaterialPropertyByName(material,"Resistivity") #  list values for Elasticity property
        if properties==None:
            Idsth.append(geo_body.Id)
        else:
            Idsthel.append(geo_body.Id)


if len(Idsthel)!=0:
    named_selection = Model.AddNamedSelection()
    selection = ExtAPI.SelectionManager.CreateSelectionInfo(SelectionTypeEnum.GeometryEntities)
    selection.Ids = Idsthel
    named_selection.ScopingMethod=GeometryDefineByType.Geometry
    named_selection.Location = selection


ExtAPI.SelectionManager.ClearSelection()


if len(Idsth)!=0:
    named_selection = Model.AddNamedSelection()
    selection = ExtAPI.SelectionManager.CreateSelectionInfo(SelectionTypeEnum.GeometryEntities)
    selection.Ids = Idsth
    named_selection.ScopingMethod=GeometryDefineByType.Geometry
    named_selection.Location = selection
