title: Why can't I remove quotes using `strip('\"')`?
body: <p>I can only remove the left quotes using <code>str.strip('\"')</code>:
  </p>
  
  <pre><code>with open(filename, 'r') as fp :
      for line in fp.readlines() :
          print(line)
          line = line.strip('\"')
          print(line)
  </code></pre>
  
  <p>Part of results:</p>
  
  <pre><code>"Route d'Espagne"
  
  Route d'Espagne"
  </code></pre>
  
  <p>Using <code>line.replace('\"', '')</code> gets the right result:</p>
  
  <pre><code>"Route d'Espagne"
  
  Route d'Espagne
  </code></pre>
  
  <p>Can anyone explain it?</p>
