flask + nginx + uwsgi - Python application not found

cat /etc/nginx/sites-available/mywebsite

server {
     listen              80;

    server_name         mywebsite;

    location /static {

from flask import Flask
app = Flask(__name__)

@app.route("/")
def index():
    return "It works!"

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

I'm running nginx, then uwsgi and has uWSGI Error 'Python application not found' in browser.
