New to Game Development - Help!

Hi! I am a college student trying to make a simple game (sudoku with a small twist) as a personal project. The backend will be written in python, not sure about the frontend yet (advice would be much appreciated!) but I will be drawing all of my assets. I'm not sure how I should publish it (a website or computer app - I don't really want to do a mobile app). I don't really have funds to pay for a server to run my python/host my website so I'm not sure what I can use for that. Does anyone have any suggestions as to what I can use to run my code? I was thinking an app might be better over a website so the save data can be stored locally. Also, should I try to use a game engine for this or is that overkill for a very simple game? Any resources/advice would be much appreciated. Thank you!
