 In order to use the python quantum client directly, you must first obtain an auth token and identify which endpoint you wish to speak to. Once you have done so, you can use the API like so::
 
+    >>> import logging
     >>> from quantumclient.quantum import client
+    >>> logging.basicConfig(level=logging.DEBUG)
     >>> quantum = client.Client('2.0', endpoint_url=OS_URL, token=OS_TOKEN)
+    >>> quantum.format = 'json'
     >>> network = {'name': 'mynetwork', 'admin_state_up': True}
     >>> quantum.create_network({'network':network})
     >>> networks = quantum.list_networks(name='mynetwork')
     >>> print networks
-    >>> quantum.delete_network(name='mynetwork')
+    >>> network_id = networks['networks'][0]['id']
+    >>> quantum.delete_network(network_id)
