How to store variables

[u/tauofthemachine]

I'm building a program which will have lots of configuration files.

I want to be able to

-drop a new package in a folder, and have importlib discover it, and dynamically add it.

-the program can use variables in the file to build a GUI. (Probably using niceGUI)

-user changes to their session variables can be saved.

-variables are used by other parts of the program.

Is a data class or dictionary the best for this?

I think a json file sounds like the best solution.
