All,
I need to log messages to both the console and a given file. I use the
following code (on Python 2.5)
import logging
#
logging.basicConfig(level=logging.DEBUG,)
logfile = logging.FileHandler('log.log')
logfile.setLevel(level=logging.INFO)
logging.getLogger('').addHandler(logfile)
#
mylogger = logging.getLogger('mylogger')
#
mylogger.info("an info message")
So far so good, but I'd like to record (possibly unhandled) exceptions
in the logfile.
* Do I need to explicitly trap every single exception ?
* In that case, won't I get 2 log messages on the console (as
illustrated in the code below:
try:
1/0
except ZeroDivisionError:
mylogger.exception(":(")
raise
Any comments/idea welcomed
Cheers.
Although it is usually not recommended to use a catch-all except, this
is the case where it might be useful. JUST DON'T FORGET TO RE-RAISE THE
EXCEPTION.
if __name__ == '__main__':
try:
main():
except Exception, e:
# log('Unhandled Exception', e)
raise
