How to log two variables values in a single logging in Python?
提问by
I am working with Python and I need to use logger so I decided to start using RotatingFileHandler. Below is my logging.conffile
我正在使用 Python，我需要使用记录器，所以我决定开始使用 RotatingFileHandler。下面是我的logging.conf文件
[loggers]
keys=root
[handlers]
keys=logfile
[formatters]
keys=logfileformatter
[logger_root]
level=DEBUG
handlers=logfile
[formatter_logfileformatter]
format=%(asctime)s %(name)-12s: %(levelname)s %(message)s
[handler_logfile]
class=handlers.RotatingFileHandler
level=NOTSET
args=('ookagent.log', 'a', 50000000000, 5)
formatter=logfileformatter
And below is my Python script from which I am successfully able to log to the files. But I am trying to log two variable values from a single logging as mentioned like below -
下面是我的 Python 脚本，我可以从中成功登录到文件。但是我试图从单个日志记录中记录两个变量值，如下所述 -
#!/usr/bin/python
import logging
import logging.config
import logging.handlers
# using RotatingFileHandler for logging purpose
logging.config.fileConfig('logging.conf')
ooklogger = logging.getLogger('')
list1 = ['abc', 'def', 'ghi']
list2 = ['jkl', 'mno', 'pqr']
ooklogger.info("Test %s" % (list1, list2))
But whenever I run my above Python script, I always get below error -
但是每当我运行上面的 Python 脚本时，我总是得到以下错误 -
ooklogger.info("Test %s" % (list1, list2))
TypeError: not all arguments converted during string formatting
Any idea what wrong I am doing?
知道我在做什么错吗？

The python logging functions support a built-in string replacement documented here. This logging supports both arg and kwarg replacement.
python 日志记录函数支持内置的字符串替换记录在这里。此日志记录支持 arg 和 kwarg 替换。
from sys import stderr
from logging import getLogger, StreamHandler, Formatter, DEBUG
l = getLogger()
sh = StreamHandler(stderr)
sh.setLevel(DEBUG)
f = Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
sh.setFormatter(f)
l.addHandler(sh)
l.setLevel(DEBUG)
L0 = ['abc', 'def', 'ghi']
L1 = ['jkl', 'mno', 'pqr']
l.info('%(list_0)s - %(list_1)s', { 'list_0': L0, 'list_1' : L1 })
# identical to
l.info('%s - %s', L0, L1)
# identical to
l.info('%s - %s' % (L0, L1))
