Is python module for global parameters good practice?

Question

I am a mechanical student and I am building physical modeling with PyODE.

instead of running everything from a single file, I wanted to organize the material in modules, so I had:

• main.py
• callback.py
• helper.py

I ran into problems when I realized that helper.py is needed to reference variables from main, but main was the only import helper!

so my solution was to create a 4th file that contains variables and only imports external modules (such as time and random).

so now i have:

• main.py
• callback.py
• helper.py
• parameters.py

and all scripts have: import parametersand use: parameters.fooor parameters.bar.

Is this an acceptable practice or is it a reliable way to make python programmers intimidating? :)

Answer 5

You should probably read Dependency Inversion .

Answer 6

It looks like you want to organize various dependencies between the components. You will be better off expressing these dependencies in an object-oriented manner. Instead of doing this by importing modules and global states, encode these states in objects and pass them.

Reading objects and classes and writing them in Python; I would probably start there.
