title: Python : How to set logging level for all loggers to INFO
body: <p>I am using following config</p>
  
  <pre><code>import logging
  
  
  FORMAT = '%(levelname)s: %(asctime)-15s: %(filename)s: %(funcName)s: %(module)s: %(message)s'
  logging.basicConfig(filename="/var/log/out.log", level=logging.INFO, format=FORMAT)
  LOGGER = logging.getLogger("Customer")
  </code></pre>
  
  <p>And then there some libraries which I have imported. Those Libraries have 
  debug logging statements like </p>
  
  <pre><code> LOGGER = logging.getLogger(__name__)
   LOGGER.debug('add_timeout: added timeout %s; deadline=%s at %s',
                       timeout_id, deadline, timeout_at)
  </code></pre>
  
  <p>When I run my program it prints debug logs of internal libraries as well.
  I want to avoid debug logs at all.</p>
