How to register two variable values ​​in one protocol in Python?

Question

I work with Python and I need to use a logger, so I decided to start using RotatingFileHandler. Below is my logging.conf file

 [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 can successfully log into files. But I'm trying to write two variable values ​​from the same log, as follows:

 #!/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 errors -

 ooklogger.info("Test %s" % (list1, list2)) TypeError: not all arguments converted during string formatting 

Any idea what I'm doing badly?

The python logging functions support the built-in string replacement described here . This log supports the replacement of arg and kwarg.

 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))
