Question about using python C module with the python module controller.

I am assuming that I can run a python C module from the python module controller, so correct me if I’m wrong on that.

My module has a function that basically does a lot. It would be run once a game frame.

So my question is, would the C module be reloaded into memory once per frame? Because that is what I want to avoid, since the C module is a large program.
