This is an alpha release of the App Engine SDK for Python 3. It provides access to various API endpoints that were previously only available on the Python 2.7 runtime.

In your requirements.txt file, add the following:

appengine-python-standard>=0.0.2a

In your app's app.yaml, add the following:

app_engine_apis: true

In your main.py, import google.appengine.api.wrap_wsgi_app and call it on your WSGI app object.

Example for a standard WSGI app:

  import google.appengine.api

  app = google.appengine.api.wrap_wsgi_app(app)

Example for a Flask app:

  import google.appengine.api
  from flask import Flask, request

  app = Flask(__name__)
  app.wsgi_app = google.appengine.api.wrap_wsgi_app(app.wsgi_app)

Then deploy your app as usual, with gcloud app deploy. The following modules are available:

• google.appengine.api.capabilities
• google.appengine.api.memcache
• google.appengine.api.urlfetch
• google.appengine.api.users
• google.appengine.ext.db
• google.appengine.ext.ndb

To install the code from the main branch on GitHub rather than the latest version published to PyPI, put this in your requirements.txt file instead of appengine-python-standard:
