ImportError using Flask and GAE

I'd like the app engine to associate index.html with the root URL and main.app with /stats. Here's my app.yaml:

runtime: python27
api_version: 1
threadsafe: yes

handlers:
- url: /
  static_files: index.html
  upload: index.html

- url: /stats.*
  script: main.app  

- url: /(.*)
  static_files: \1
  upload: (.*)

If the URL is /stats, I'd like to print a short message. Here's the code in main.py:

import logging
from flask import Flask

app = Flask(__name__)

@app.route('/stats')
def stats():
    return 'Hello World!'

When I try to access /stats, the GCP log says ImportError: No module named main. How can I fix this?

Looks like you entered in a conflict between the /stats handler and the /(.*) handler. As per the documentation for static_files:

If a static file path matches a path to a script used in a dynamic handler, the script will not be available to the dynamic handler.

So, either remove the /(.*) handler, or, as you intent to serve static files with it, I recommend using a handler like the one described in the documentation: 

- url: /(.*\.(gif|png|jpg|whateverextension))$
  static_files: static/\1
  upload: static/.*\.(gif|png|jpg|whateverextension)$

Also, don't forget to add the Flask library to your app.yaml file: 

libraries:
- name: flask
  version: 0.12
