Learn logging module of Python
There are more information on the internet about logging module of python, but I just record the part I used. So, if you want to learn more about it, you can search another information on the internet by Google.

basic-config
# -*- coding:utf-8
# python3
import logging
logging.basicConfig(filename='logging.log',
format='[%(asctime)s:%(levelname)s]:%(message)s',
level=logging.INFO)
logging.info('start logging')
when you check the file logging.log
, you can see the output like this [2017-09-08 18:05:33,373:INFO]:start logging
print one log-file by multi-script
If you want to print logging into one log-file by multi-script, you can use the object logger
.
For example, if you have two python script.
other.py
# other.py
# -*- coding:utf-8 -*-
# python3
import logging
logger = logging.getLogger('main.other')
logger.info('this is other info')
logger.warning('this is other warning')
logger.error('this is other error')
main.py
# main.py
# -*- coding:utf-8 -*-
# python3
import logging
import other
logging.basicConfig(filename='logging.log',
format='[%(asctime)s:%(levelname)s]:%(message)s',
level=logging.INFO)
logger = logging.getLogger('main')
logger.info('this is main log info')
logger.warning('this is main warning')
if you run main.py
, you will create a new file logging.log
, open it, you can see:
[2017-09-08 18:05:33,373:INFO]:this is main log info
[2017-09-08 18:05:33,373:WARNING]:this is main warning
[2017-09-08 18:05:33,373:INFO]:this is other info
[2017-09-08 18:05:33,373:WARNING]:this is other warning
[2017-09-08 18:05:33,373:ERROR]:this is other error
