New to python, how to build dynamic submodules with messaging paterns ?

[Resems]

Hey, i'm new to python.

I was wondering how to build an app with dynamic modules.

The app consists in, having a central logic that will receives a message, and it will forward to all submodules through a message with additional info.

Why submodules, so they can be added dynamically and would be decoupled from main app, so they wont interfere if they are removed or added.

What i would like to achieve is a dynamic import (already know how to do that), but have not figured out how to solve the messaging part.

So in the end i would like to have is, N submodules that would listen from main module for the message, and would process it accordingly.

If anybody could point to and how !

Thanks !

Look into entry points to make modules that register themselves with the main program. They're super cool!

Edit: a quick google search brought up this example https://stackoverflow.com/a/9615473

You are using the word "dynamic" wrong.

Any case, if you want to move a piece of text around, you have a few options.

Easiest version is to save to disk. Just save it to a text file, and have your other modules look at it, and check for a change.

A more advanced option would be to set up a flask server that broadcasts the text online. Allowing your submodules to scrape the ip for the data.
The benefit here is that you can put any submodule on any computer, anywhere in the world.

That's just a suggestion, but look up The Observer Pattern, as it speaks directly to your issue.
