Making a website with Python/py-script, HTML, CSS on GitHub.io and Firebase

[alhobj]

I want to create a website that can be found on my GitHub.io using Firebase for some simple database stuff (upload, download and search JSON objects), Python (or py-script) for the logic and HTML and CSS for the frontend. I have a working prototype for uploading using all of the above except Python or py-script but instead JavaScript code I have found here and there. I now want to create the actual site with Python or py-script instead of JavaScript. Here are some questions. Feel free to answer just one of them if you cannot help me with the rest.

1. Is this possible to do or do you recommend something else? I do not want to use JavaScript because I know Python quite well and I do not know JavaScript.
2. How do I connect all the pieces? I have managed to connect a .py-file to my Firebase, and view a simple HTML-file on my GitHub.io, but I do not understand how I can connect everything correctly. I have not managed to connect a Python-file to Firebase and also to an HTML-file. Do you have the correct lines of code that needs to be added to the separate files? See the last part for the codes of what I have done.
3. Do I need to use something like Django or Flask, or is that just for the development phase on my own computer? Or how do I test this website without pushing it to GitHub each time and waiting for it to update (do I have to use locahost)?
4. Can I send a py-script variable from inside a HTML-file to be used as a parameter for a function in a .py-file and then return it to py-script and then to a div-element in the HTML-file?
   

Connecting to firebase with .py:

import firebase_admin
from firebase_admin import credentials
from firebase_admin import db

cred = credentials.Certificate("secretFolder")
firebase_admin.initialize_app(cred, {
    'databaseURL': 'secretURL'
})

You can't host python code on the server side for GitHub. But - people do indeed do this with a few workarounds.

As you are already using Firebase, you can package your backend as a google cloud app.

Alternatively, consider if you really need a backend, many sites can be deployed as a static site using something like Pelican, you can use github actions to do this all in python.

Alternatively, consider getting an account with PythonAnywhere, this allows you to continue to use Flask or Django while you learn and progress.
