Front-end for a simple python tool

I have no experience in front-end coding (Java, HTML, CSS), and I want to know What I have to know For a personal project of mine.

I have created a Python tool that records some data and parameters of the users and performs a value and analysis for them. This is a tool for a game that I play, which scores and evaluates the equipment of a user.

Running on Python, currently it is a text -based interface. More people will want to test and use this tool if it actually had a GUI, and don’t have to download anything on their PC and use it directly from a website.

It seems that websites such as Pythonanywhere can host a web app for free. But I still don’t know where to start.

I am not looking for authentication or storing user data or something similar – it is a simple “ask a question, get an answer” Type, except that “just” what is the value of the data/parameters? “, Which is given to the Python code, processed and numerieke and text -based analysis has been provided.

I would like it to be somewhat modern and allow a little cool design. Because it is for a game, it would be possible to allow some character images and other stylistic/artistic functions are also fun. And some graphic display techniques such as the progress bar, or bar chart or pie chart etc. would also be fun.

I just don’t even know what to know to make a decision about what to learn and how in -depth to learn it.

If this is too vague of a question, guidance on what I should investigate is also appreciated. Thank you in advance!
