URL String with parameters

I want to make App without framework ( it is tiny background app).

To make it very clear you don't want to that and CGI is dead it will be removed.

cgi is going to be deprecated in Python 3.8 and removed in 3.10

So the modern way to do CGI in Python is the use a smaller web-framework like Flask, Bottle, ect...
Python community has written WSGI(all Python code) to replace CGI(had a lot of problems that could not be fixed).

So eg Flask is layer above WSGI to make all easier connect to web with HTML/CSS than using WGSI directly.
