A suds client as two major components: the "service" itself, and
the so called "factory". You can use the "factory" to create Python
objects corresponding to a type defined in the WSDL.

To pass a list of complex type, you use the factory to
create Python objects for the list components, set these objects'
attributes in any way appropriate and build of Python list of
them and assign the list or "append" them directly to the list
values attribute.

In your case, it may look somehow like:

   sd = client.factory("SubscriberDataType") # create a SubscriberDataType Python object
   sd.SubscriberID = ... # assign values for its attributes
   ....
   mrr = client.factory("MedicalRatingRequest")
   mrr.SubscriberData.append(sd) # append our "sd"
or
   mrr.SubscriberData = [sd] # assign a list
