run python script on heroku

1Sure, you need to do a few things:
2
3Define a requirements.txt file in the root of your project that lists your dependencies. This is what Heroku will use to 'detect' you're using a Python app.
4
5In the Heroku scheduler addon, just define the command you need to run to launch your python script. It will likely be something like python myscript.py.
6
7Finally, you need to have some sort of web server that will listen on the proper Heroku PORT -- otherwise, Heroku will think your app isn't working and it will be in the 'crashed' state -- which isn't what you want. To satisfy this Heroku requirement, you can run a really simple Flask web server like this...
8
9Code (server.py):
10
11from os import environ
12from flask import Flask
13
14app = Flask(__name__)
15app.run(environ.get('PORT'))
16Then, in your Procfile, just say: web: python server.py.
17
18And that should just about do it =)
