How can I deploy my python program on the web? ---------------------------------------------- I

have a .py program that uses some external modules; takes a file as input, and stores the output in another file.
I want to create a webpage that contains two textarea boxes (one for input and one for output) and a button (which should trigger the .py program in the backend).
I can't use javascript because the module I'm using is PRAW (works with python only).
----
I have tried using Brython, but it does not import a whole folder as a module(PRAW is not a single .py file, code is distributed across multiple files and folders) https://brython.info/static_doc/en/import.html
----
Is there any other way to deploy my python program on the web?
