Basically, never configure or add handlers to any logger except for the
root logger in your __main__ section. There are very few reasons why you

module you'll when to break it.
I have never used logging, but if and when I have a need for it, the
advice above and your clear example will be a good guide to getting
started. Thank you from me too.

[server.py]
import logging

logger = logging.getLogger(__name__) # you'd better to create the logger
at the module level, you may want to log within the module function

self.logger = logger

self.logger.warning('This message comes from Server module ')
[client.py]
import logging

from server import Server
logger = logging.getLogger(__name__)

self.logger = logger

self.logger.warning("This message comes from Client module")
if __name__ == "__main__":
rootLogger = logging.getLogger()
rootLogger.addHandler(logging.FileHandler("client.log"))
rootLogger.handlers[-1].setFormatter(logging.Formatter("%(asctime)s

cli.client_test()
Happy logging,
