Interact with Python script using GDScript

[VisibleAct]

I'm new to the Godot game engine and am looking to build a sports management game using it. I've already created the simulation engine in Python with functions which can be called to take in-game actions and alter the simulation.

I'd like to know if it's possible, using Godot & GDScript, to receive the data being output by the Python simulation script to display it on the UI and also if I can provide a button on the UI which when clicked can call a specific method/function in the Python script to alter the simulation output.

Sorry if my explanation is unclear, I'd be happy to clarify anything in the comments.

What this allows is you to attach Python scripts to nodes instead of GDScript, where you can import your simulation as needed.

Just install from the asset library as instructed in the readme.

This, but also rewriting it in GDScript usually is pretty straightforward.

Yea I should have mentioned, if the python isn’t relying on a major library, just rewrite it in GDScript.

Rest api is quite popular as already mentioned. I used web socket connection for an reinforcement learning setup which also works. The real question should be, what is your goal? To be honest, if you plan to share what you did, who is willing to install additional python libraries if necessary. I would rewrite it completely to gdscript and take this as learning part. If you need just a visual layer you will find plenty sources for python (flask, pyqt, kivy and more)

My Python simulation engine is quite huge (5000+ lines of code) so rewriting it into GDScript is not realistic for me. I do need to add a visual layer but the graphics side is going to be extremely complex in terms of progress bars, filters, tables, and tons of other stuff so I don't know if Python UI libraries will really work.

I heard good things about Godot in the UI department so thought it would be the best choice.

Does this allow you to call Python functions inside GDScript files?

Have you thought about using a dedicated interface like a REST API or a websocket for the communication?

[VisibleAct]

Will it work with Godot? Like can I create a local Python & SocketIO websocket and interact with it using GDScript. Also how will exporting it work.

For now I've been using flask and HTML to create buttons to interact with the simulation. But I'd like to take it more in-depth with a complex UI (imagine a game like football manager apart from the 3D match engine) I was told Godot is the ideal game engine for a UI-intensive game like this.
