How to do it in python?

Question

Python

Hello. I'm not very familiar with the possibilities of Python.
I want to write a script in python that will listen to incoming http requests in json format on a specific port, process them and return json back as a response.
Having received a json request, I will parse it, connect to the PostgreSQL database, add a record, and return the success of the operation in json.
I'm not asking how to do it, my question is which libraries to use.
It will be a console application, constantly running and listening on the port.
I'd be grateful if you point me in the right direction

Answer 1

nginx + uWSGI:
  flask: raw_sql or sqlAlchemy
  or
  django

Answer 2

If the requests are of the same type and not very complex - the TCP library. Provides raw sockets. We listen to the port, parse the data and further down the list. Well, or full-fledged http frameworks, and la django or flask
For json, the json library =)
