That are two distinct aspects. You may specify both what is logged and where
it is logged.
The easiest way to set up the filter is again basicConfig():
$ python3 -c 'from logging import *; basicConfig(); warn("important");
info("nice to know")'
WARNING:root:important
While the default level is WARNING you may specify something else:
$ python3 -c 'from logging import *; basicConfig(level=INFO);
warn("important"); info("nice to know")'
WARNING:root:important
INFO:root:nice to know
