title: How to write very long string that conforms with PEP8 and prevent E501
body: <p>As PEP8 suggests keeping below the 80 column rule for your python program, how can I abide to that with long strings, i.e.</p>
  
  <pre><code>s = "this is my really, really, really, really, really, really, really long string that I'd like to shorten."
  </code></pre>
  
  <p>How would I go about expanding this to the following line, i.e.</p>
  
  <pre><code>s = "this is my really, really, really, really, really, really" + 
      "really long string that I'd like to shorten."
  </code></pre>
