API/SDK: List files in ISO domain

I recently started messing with the Python SDK and was wondering if someone could help me figure out how to list the files in the ISO domain.  Using cURL I can achieve the desired result with the following command:

curl --cacert rhevm.crt -u "$credentials" -H "Content-Type: application/xml" -X GET https://$host/api/storagedomains/$domain_id/files

What is the equivalent to this in the Python SDK?
