title: Is there a way to change the filemode for a logger object that is not configured using basicConfig?
body: <p>If I create a logger object by using logger = logging.getLogger("Name") I am unable to change the filemode from append('a') to write ('w'). I can if I use the root logger with basicConfig, but then I get a lot of system debug messages being logged when all I want is my own messages beginning at the DEBUG level.</p>
  
  <p>I am hoping to either (1) change the filemode for my own logger object to 'w'
  or (2) add a filter to the root logger. Is it even possible to filter out these debug messages from the root logger?</p>
  
  <pre><code>def create_log():
      # create logger for "Sample App"
      logger = logging.getLogger('automated_testing')
      logger.setLevel(logging.DEBUG)
  
      # create file handler which logs even debug messages
      fh = logging.FileHandler('results.log')
      fh.setLevel(logging.DEBUG)
      # create console handler with a higher log level
      ch = logging.StreamHandler(stream=sys.stdout)
      ch.setLevel(logging.DEBUG)
      # create formatter and add it to the handlers
      formatter = logging.Formatter('[%(asctime)s] %(levelname)8s --- %(message)s ' +
                                    '(%(filename)s:%(lineno)s)',datefmt='%Y-%m-%d %H:%M:%S')
      fh.setFormatter(formatter)
      ch.setFormatter(formatter)
      # add the handlers to the logger
      logger.addHandler(ch)
      logger.addHandler(fh)
  
      return logger
