Take a look at the restapi structure of api/vms/{vm-id}/statistics for 
pointers, but basically here is a simple example:

for stat in api.vms.get('my_vm').statistics.list():
     print 'Name:', stat.name
     print 'Description:',stat.description
     for value in stat.values.value:
         print '  Value:', value.datum
