How to create a system of events through interrupts in python

Because of my zero knowledge about Python GUIs,
I need some help, to make a mechanism for,
Making requests through HTML,CSS or Ajax (node.js, Apache or nginx server) to a Python program to execute certain functions.

For example,
I have a python running a while True: loop, but at a given moment want perform an interrupt signal and sending data to execute a function a kind of events system.

First, I bind an event to program: 

#program.bind(EVENT_NAME, EVENT_HANDLER)
program.bind(miaowcat, miaowfunc)

The program runs and any time an interrupt is performed, executing the function miaowfunct and passing the data of the event to *args

def miaowfunct(*args):

It's a prototype. So, args can be with numeric signals or other elements.

I don't know how to do this.

This kind of problem is what messaging systems are designed to solve.

You write some code that needs to be executed at a trigger (this is called a consumer).

Your code that needs to execute the function (called a producer), creates a message and sends it to a broker.

The broker takes your message and puts it on a queue.

The consumer is listening on this queue for messages, when it sees one, it will "wake up", run itself, and then go back to sleep.

For Python, the following are typically used:
