Yes, We would be interested in doing that.
Please let me know which is the right group/ team for this?

Do you have plans to submit these back upstream? It would be a great first start, perhaps we could add these as examples underneath the JSON request/reponse in http://api.openstack.org/api-ref-networking.html

Sean,
We have written a few docs for writing these samples

http://python-api-guide.cfapps.io/content/neutron.html


You can find get the source here https://github.com/rajdeepd/openstack-samples

Thanks

Hi,

I was writing a small script yesterday to parse a list of IP blocks and
create security groups and rules, by using python-neutronclient.

To be honest, it was very difficult - even though I have actually
written extensions to Python-Neutronclient for the QoS API. 

For those that are trying to use the client from inside their code,
they end up getting zero help as to how to actually call any of the
functions, and what parameters they take. 


    >>> neutron = client.Client('2.0', auth_url=os.environ['OS_AUTH_URL'],
    ...                            tenant_id=os.environ['OS_TENANT_ID'],
    ...                            username=os.environ['OS_USERNAME'],
    ...                            password=os.environ['OS_PASSWORD'])
    >>> help(neutron)

  |  create_credential = <function with_params>
  |  
  |  create_firewall = <function with_params>
  |  
  |  create_firewall_policy = <function with_params>
  |  
  |  create_firewall_rule = <function with_params>
  |  
  |  create_floatingip = <function with_params>
  |  
  |  create_health_monitor = <function with_params>
  |  
  |  create_ikepolicy = <function with_params>
  |  
  |  create_ipsec_site_connection = <function with_params>
  |  
  |  create_ipsecpolicy = <function with_params>
  |  
  |  create_member = <function with_params>
  |  
  |  create_metering_label = <function with_params>


Since there was nothing there, I decided to go check the source of
python-neutronclient and see if there are any examples.

https://github.com/openstack/python-neutronclient/blob/master/doc/source/index.rst

If you read closely enough, you'll find out that the function takes a
dictionary, that looks very similar to the request/response examples
listed in the API documentation. So, I went over and checked it out.

http://docs.openstack.org/api/openstack-network/2.0/content/POST_security-groups-v2.0_createSecGroup_v2.0_security-groups_security-groups-ext.html

So from there, I was able to remember enough that each of these
functions takes a single argument, that is a dictionary, that mimics
the same structure that you see in the API documentation, so from there
it was just some experimentation to get the structure right.

Honestly it wasn't easy to remember all this stuff, since
it had been a couple months since I had worked with
python-neutronclient, and it had been from inside the library itself.

This was my first experience using it "on the outside" and it was pretty
tough - so I'm going to try and look into how we can improve the
docstrings for the client object, to make it a bit easier to figure out.

Thoughts?
