The AdWords API Python Google App Engine demo has been updated to use 
v201109 (and 
clientCustomerId) and now has its source control hosted at the new 
project site.
In addition, we are happy to announce the release of a new 
Python Google App Engine demo - this one demonstrating 
AdHoc reports running on Google App Engine using OAuth 1.0a for the authentication.  This demo allows you to select as many or as few child accounts as you wish to run a report against and will download the reports asynchronously using a 
Task Queue one by one.  Reports are stored in the Google App Engine 
Blobstore and can be downloaded by the user once they have been processed.
The new demo also shows how to perform the 
OAuth flow in a web application context and how to store the oauth_token and oauth_token_secret in the Google App Engine datastore.  OAuth is used both to query the API for a list of accounts as well as to download the reports.
You can download the Google App Engine demo and use the 
Python Development Google App Engine Server to play around with the code without the need for an existing Google App Engine account.  If you have any questions or would like to discuss this new demo, please post on 
the forum.
