How to get parent type in wsdl using suds?

Question

Python

Tell me how can I create the correct xml to send via sudl wsdl.
My problem is that I can't figure out how to get
type="tns:ItemType" from methods. because when creating client.factory.create(types)
, the following elements are created:

ParcelType: (ParcelType){
   item[] = <empty>
   _barcode = ""
   _weight = ""
   _volume = ""
 }

ItemType: (ItemType){
   _sku = ""
   _barcode = ""
 }

As we can see, in order to create a ParcelType we have to create an ItemType and then shove them
into item[].
I would like to get type="tns:Type" information so that I can create a type tree and
go from the deepest to the topmost type. Tell me how to get
this information in suds.
