logging module question

[s99999999s2003@yahoo.com]

hi
i have defined a function
def logger(logfile, msg):
import logging

logging.basicCo nfig(level=logg ing.DEBUG,
format='%(ascti me)s %(levelname)-8s
%(message)s',
datefmt='%a, %d %b %Y %H:%M:%S',
filename='%s' % (logfile),
filemode='a')
logging.critica l(msg)
logging.error(m sg)
logging.warning (msg)
logging.info(ms g)
logging.shutdow n()

In my main code:

----- some python code here---
logger("test.lo g","error")
......
......
logger("test.lo g","another error")
....
logger("test.lo g","yet another error")
....
sys.exit(0)

When i do the above, i get :
self.stream.wri te(fs % msg)
ValueError: I/O operation on closed file

If i removed logging.shutdow n(), it workds..what is wrong with my
function ?
thanks

Why log the same message with different severity ?

Why exactly do you call logging.shutdow n() when you use the logging system
again with further calls to logger().

As far as I see it logging.shutdow n() should only be called when you're
done with logging alltogether. However in your case you probably don't
need to call it at all since it's invoked automatically when yout program
exits.
