title: Issues using strip() on a variable
body: <p>I'm trying to strip the characters <code>b,'()</code>.
  The issue I'm having is that it says TypeError 'str' does not support the buffer interface. </p>
  
  <p>Here are the relevant parts of code in this:</p>
  
  <pre><code>import urllib3
  def command_uptime():
  
      http = urllib3.PoolManager()
      r = http.request('GET', 'https://nightdev.com/hosted/uptime.php?channel=TrippedNW')
      rawData = r.data
      liveTime = bytes(rawData.strip("b,\'()", rawData))
  
      message = "Tripped has been live for: ", liveTime
      send_message(CHAN, message)
  </code></pre>
