Python을 기반으로 로그를 여는 올바른 방법

import os
import logbook
from logbook.more import ColorizedStderrHandler
import smtplib
LOG_DIR = os.path.join('log')
if not os.path.exists(LOG_DIR):
  os.makedirs(LOG_DIR)
def get_logger(name='test', file_log=False):
  logbook.set_datetime_format('local')
  ColorizedStderrHandler(bubble=False).push_application()
  if file_log:
    logbook.TimedRotatingFileHandler(os.path.join(LOG_DIR, '%s.log' % name), date_format='%Y%m%d', bubble=True).push_application()
  return logbook.Logger(name)
LOG = get_logger(file_log=True)
def send_email(email_conf, message):
  smtp = smtplib.SMTP()
  smtp.connect(email_conf['host'], email_conf['port'])
  smtp.login(email_conf['user'], email_conf['password'])
  smtp.sendmail(email_conf['fromaddr'], email_conf['recipients'], message.as_string())

from logger import LOG 
 
if __name__ == "__main__": 
  LOG.info('Checking %s:%s ...' % (str(date), str(data_type)))
