How to proxy a website in python?

Question

Python

Hello. Nginx has a proxy_pass setting to proxy traffic to the desired host. Is it possible to implement something like this in python. Or I use the same nginx, but with preprocessing (html) documents. Everything should work with support for user sessions.
There is site A and I need to proxy it to another domain with a change in html.
I see it this way: Nginx (receives requests) -> python (processes html) -> then the user sees the final html.
