Pause in a loop

[manuel]

I've two modules: main.py and eval.py

Eval.py is imported in main.py, but I've a loop
in eval.py that must call a function in main.py...

I can't import main.py in eval.py too, because
that would create an import loop.

But I'm thinking a different solution:
a pause in a loop to return periodically an
output. It's possible?


thanks,
