Getting a Python/Flask app running on Webfaction

index.py

# Follow instructions here: http://flask.pocoo.org/snippets/65/
# You'll need to make sure you have the right Python version and any packages installed: http://docs.webfaction.com/software/python.html
# This tweak to index.py is what made it actually work: http://stackoverflow.com/questions/3696606/how-to-solve-import-errors-while-trying-to-deploy-flask-using-wsgi-on-apache2

import sys
yourappname = "/home/username/webapps/yourappname/htdocs"
if not yourappname in sys.path:
    sys.path.insert(0, yourappname)

from yourappname import app as application

yourappname.py

from flask import Flask
app = Flask(__name__)

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

if __name__ == '__main__':
    app.run()

You could also just drop your app into /home/username/webapps/yourappname/lib/python2.7/ since that's already in sys path.
