title: Match unescaped quotes in quoted csv
body: <p>I've looked at several of the Stack Overflow posts with similar titles, and none of the accepted answers have done the trick for me.</p>
  
  <p>I have a CSV file where each "cell" of data is delimited by a comma and is quoted (including numbers). Each line ends with a new line character. </p>
  
  <p>Some text "cells" have quotation marks in them, and I want to use regex to find these, so that I can escape them properly.</p>
  
  <p>Example line:</p>
  
  <pre><code>"0","0.23432","234.232342","data here dsfsd hfsdf","3/1/2016",,"etc","E 60"","AD"8"\n
  </code></pre>
  
  <p>I want to match <strong>just the <code>"</code></strong> in <code>E 60"</code> and in <code>AD"8</code>, but not any of the other <code>"</code>.</p>
  
  <p>What is a (preferably Python-friendly) regular expression that I can use to do this?</p>
