title: 'str' object has no attribute 'decode' in Python3
body: <p>I've some problem with "decode" method in python 3.3.4. This is my code:</p>
  
  <pre><code>for lines in open('file','r'):
      decodedLine = lines.decode('ISO-8859-1')
      line = decodedLine.split('\t')
  </code></pre>
  
  <p>But I can't decode the line for this problem: </p>
  
  <pre><code>AttributeError: 'str' object has no attribute 'decode'
  </code></pre>
  
  <p>Do you have any ideas? Thanks</p>
