A look at web hosting and options for hosting your Python code, in particular a VPS which will give you full root access. Webdock.io is what I will be using for running a Django based site with Nginx and Gunicorn.
Whilst Django is a framework, the idea is to not rely on yet another 'framework' such as Heroku or any hosting provider that makes deploying your code too easy. "Don't be lazy" !
By configuring your own server and installing your own version of Python you will have total control and no unexpected usage bills.
