I will commonly put something like:
logger = logging.getLogger("logger-name-for-my-module")
in every source file in a big project. Now I've got a global logger I
can use anywhere in the module (even in static functions). But, maybe
that's just a subset of your "setting that gets set once at the start of
the program" example.
