You should be able to use the existing python client libraries. According to the docs:
"""Token object for OAuth 2.0 as described on <http://code.google.com/apis/accounts/docs/OAuth2.html>. Token can be applied to a gdata.client.GDClient object using the authorize() method, which then signs each request from that object with the OAuth 2.0 access token. This class supports 3 flows of OAuth 2.0: Client-side web flow: call generate_authorize_url with `response_type='token'' and the registered `redirect_uri'. Server-side web flow: call generate_authorize_url with the registered `redirect_url'. Native applications flow: call generate_authorize_url as it is. You will have to ask the user to go to the generated url and pass in the authorization code to your application. """ If I have a chance, I can try to put together some sample code that will do this.
