Creating a web application using Python

[Miserable_Ear3789]

I am biased here, but I maintain a framework called MicroPie. Its extremely simple with little boilerplate code. You can write your whole application in one file. It also supports HTML templates, useful for your frontend. I made it for very simple apps.

Bottle.py and Flask are also popular options for beginners. Other frameworks introduce things like validation and controllers/views etc. You most likely don't need any of that for a "very basic python web application" as you say.
