Hi Soltys,
I actually tried that, without any noticeable effects, viz.:
$ cat server.py
import logging
import logging.handlers
class Server():
def __init__(self):
self.client_logger = logging.getLogger("client")
self.client_logger.setLevel(logging.DEBUG)
h = logging.FileHandler("client.log")
h.setLevel(logging.DEBUG)
formatter = logging.Formatter("%(asctime)s %(name)-12s %
(levelname)-8s %(message)s")
h.setFormatter(formatter)
self.client_logger.addHandler(h)
self.client_logger.propagate = 0
def util(self):
self.client_logger.warning('This message comes from Server
module')
$ cat client.py
import logging
import logging.handlers
from server import Server
class Client():
def __init__(self):
self.client_logger = logging.getLogger("client")
self.client_logger.setLevel(logging.DEBUG)
h = logging.FileHandler("client.log")
h.setLevel(logging.DEBUG)
formatter = logging.Formatter("%(asctime)s %(name)-12s %
(levelname)-8s %(message)s")
h.setFormatter(formatter)
self.client_logger.addHandler(h)
self.client_logger.propagate = 0
def client_test(self):
self.client_logger.warning("This message comes from Client
module")
if __name__ == "__main__":
ser = Server()
cli = Client()
ser.util()
cli.client_test()
$ rm client.log ; python client.py ; cat client.log
