Google App Engine Samples

http://code.google.com/p/google-app-engine-samples/wiki/GoogleAppEngineSamples

Introduction

This project contains sample code that can be run on Google App Engine. Each sample is checked in its own directory in the project's trunk. The samples highlight parts of the Google App Engine APIs, including samples that integrate Google App Engine with other web tools and APIs.

Details

Samples:
trunk/geodatastore: The GeoDataStore application allows you to store you geo data on the App Engine infrastructure. It comes with a backend server which can be accessed directly using Get and Post, as well as a Google Maps API front-end.
trunk/myhangouts: My Hangouts is a simple ajax applications that provides a simple RPC framework for making mostly abstract Python function calls from JavaScript. Provides a few simple functions for the My Hangouts application.This application uses the lower level Datastore API to make datastore calls and perform queries.
trunk/secret_valentine: Secret Valentine is a demo of the mail api. Users fill out a form to send an email to a friend. The application replaces the form content with some secret content and sends an email to the specified user.
trunk/tasks: The Tasks application is a stylized task list. Its a collaborative task application that enables users to share task lists with one another and provides a simple access control mechanism.
trunk/muvmuv: MuvMuv is a simple movie review site that grabs the upcoming movies and find its movie trailer.
trunk/blitz: Blitz is an Ajax chess program with real time chat and persistent storage of game history.
trunk/shell: An interactive, stateful AJAX shell that runs Python code on the server. Deployed at shell.appspot.com.
trunk/openid-provider: An OpenID provider. Allows Google users to log into OpenID consumer sites using their Google Account. Deployed at openid-provider.appspot.com.
trunk/indexed-cached-zipserve: Allows serving static files from zip files. Uses memcache to increase performance. It performs best when files zipped in alphabetical order so the handler can easily determine which zip file a given url is in.
trunk/guestbook_namespaces: Namespace aware sample guestbook application for python App Engine. (Needs 1.3.6 or higher App Engine SDK)
trunk/gwtguestbook-namespaces: Namespace aware sample guestbook application for GWT/Java App Engine. (Needs 1.3.6 or higher App Engine SDK)

Google app engine launcher: Invalid username or password

I've download google app engine (python) for windows and install it. Then I went to console.developers.google.com/project and create new project. After that, I launched google app engine launcher, create new application and named it as project I have recently create. I click on deploy and constantly getting this error:
  03:35 PM Application: udacity-hello-pozdrav; version: 1
03:35 PM Host: appengine.google.com
 03:35 PM 
Starting update of app: udacity-hello-pozdrav, version: 1
03:35 PM Getting current resource limits.
Password for t******.****@gmail.com: Invalid username or password.
2014-09-06 15:35:56,690 ERROR appcfg.py:2411 An error occurred processing file '': HTTP Error     401: Unauthorized. Aborting. 
  Error 401: --- begin server output ---

  --- end server output ---

You can close this window now.
I've read about appcfg.py but when I enter it in cmd, It says that it's not recognized.
Answer:
 Well, in floundering around I've found an answer.
I went here: https://www.google.com/settings/security/lesssecureapps
and selected "Enable" less secure devices and apps to access your data. When I tried to Deploy - it worked.


Less secure apps

Some devices and apps use insecure sign-in technology to access your data.
Choosing Disable prevents these less secure devices and apps from accessing your Google Account.
Choosing Enable increases your chances of unauthorized account access but allows you to continue using these less secure devices and apps. Learn more

It's probably because Google's datastore indexes aren't updated yet. Wait a little while and it should work. Google explains it here
Note: The Datastore Indexes may take some time to generate before your application is available. You will receive a NeedIndexError when accessing your app if the indexes are still in the process of being generated. This is a transient error for the example, so try a little later if at first you receive this exception.
