How does a logger work in Python?

Question

Python

Suppose I have two modules app.py and foo.py
I understand correctly that it is enough for me to configure the logger in the app.py module like this:

logging.basicConfig(level=logging.INFO)
log = logging.getLogger()
handler = logging.handlers.SysLogHandler(address='/dev/log') # or logging.StreamHandler()
log.addHandler(handler)

After that, in order for my logger to work exactly as specified in the foo.py module, I just need to initialize it there:
log = logging.getLogger()
And will it use the settings from the app.py module or are there any nuances?
