Is it possible to run a notepad file through your computer and have others be able to access that file like on a server using python code alone?

Im aware that this will either be a very obvious no or a very complicated yes, but I’m wondering if it’s possible to run a notepad file on another computer without having the file. The idea is to make a game with a bazaar or auction house type market with that being the only multiplayer feature. I’m wondering if it is possible for others to write to the file on my pc when selling (I’m aware it would have to be turned on as it would run like a server pc) and have other players be able to read and remove text from the file, so in essence have remote pcs run one file. If it is possible, is there a way to run it through python?
