title: logging level vs handler level
body: <p>What is the difference between setting the logging level from the logger and from the handler?</p>
  
  <p>The following code:</p>
  
  <pre><code>myLogging = logging.getLogger('myOp')
  myLogging.setLevel(10)
  hdlr = logging.FileHandler(myLogFile)
  myLogging.addHandler(hdlr)
  myLogging.debug("Message here")
  </code></pre>
  
  <p>will log to <code>myLogFile</code>, but this other one won't:</p>
  
  <pre><code>myLogging = logging.getLogger('myOp')
  hdlr = logging.FileHandler(myLogFile)
  hdlr.setLevel(10)
  myLogging.addHandler(hdlr)
  myLogging.debug("Message here")
  </code></pre>
  
  <p>Why is it that the <code>FileHandler.setLevel()</code> won't write to <code>myLogFile</code>?</p>
