How to store environment variables in a Python Flask app?

Question

I have a Python Flask app that accesses the Github API. For this I need to store an access token. What is the common practice to store that data and how do I access that inside my app?

from flask import Flask, request

app = Flask(__name__)
app.config['DEBUG'] = True


@app.route('/',methods=['POST'])
def foo():
   ...

Flask has a custom context to store app variables:

http://flask.pocoo.org/docs/1.0/appcontext/

You can use g object to store your variables:

from flask import g
g.github_token = 'secret'

And after initialization:

from flask import g
token = g.github_token
