Python and Flask: notes and background exports

You will use Python 3.13 and build a web app named notes-web plus a worker named notes-worker in the examples Project’s python Environment.

Flask defines the routes and Gunicorn serves them in the deployed web process. Psycopg, PyMySQL, and PyMongo handle persistence. The committed Procfile is required by the Python builder.
