python logging into file as well as wxpython txt ctrl

How can I log into a file as well as to to wxpython txt ctrl ?

Background I have wxpython GUI based application which enumerates python test files and executes them. With the help of http://broadcoder.blogspot.com/2009/10/redirecting-python-logging-to.html I was able to redirect python logging messages to the txtctrl. However I will also like to redirect logging messages to log files also. I import my testfiles like this:

     logging.info('Started')
     testid = __import__(str)
     reload(testid)

     testOut = testid.main()

In each of my testfiles I simply use import logging and my logging messages get redirected to the txt ctrl. However I would also like that the test log messages also be redirected to a log file based on the name of the file. How do I redirect my log messages to both? If I use logging.basicConfig in my test file messages are still directed only to the text ctrl. My TestGUI.py in which I import say 5 python test files. In my test file files I simply use import logging while I setup the logger in my TestGUI.py file 

    self.logr = logging.getLogger('')
    self.logr.setLevel(logging.INFO)
    hdlr = WxLog(self.log)
    hdlr.setFormatter(logging.Formatter('%(message)s '))
    self.logr.addHandler(hdlr)

In my test file I do something like this:

      logger = logging.getLogger('')   
      fh = logging.FileHandler("log.html",mode='w')
      formatter = logging.Formatter('%(message)s')
      fh.setFormatter(formatter)
      logger.addHandler(fh)
      a= 5
      b= 6

      logging.info('a=5')
      logging.info('b=6')
      c= a+b
      logging.info('adding b and  c')
      fh.close()

I get ValueError: I/O operation on closed file when I run this test more than once .

One Logger can have multiple handlers ! so you can achieve this easily.

example 

import logging
logger = logging.getLogger('myapp')
hdlr = logging.FileHandler('var/myapp.log')
hdlr2 = logging.FileHandler('var/myapp2.log')
formatter = logging.Formatter('%(asctime)s %(levelname)s %(message)s')
hdlr.setFormatter(formatter)
hdlr2.setFormatter(formatter)
logger.addHandler(hdlr)
logger.addHandler(hdlr2)
logger.setLevel(logging.INFO)
logger.info('a log message')
