Call Python from Meteor

I’d like to build a Meteor app that calls a Python script. The Python script will read and write to/from the same Mongo database that the Meteor app uses.

Looking at this Stack Overflow answer this seems fairly easy:

However, I’m wondering how hard it would be to deploy this (devops is not my strong side). What provider would you use it you were to do this, and does anyone have any idea if the coming Galaxy from MDG will make it possible to include scripts in other languages than JS?
