title: Replace specific character from the list of string
body: <p>Gurus,</p>
  
  <p>I have list which looks like following : </p>
  
  <pre><code>[u'test1', u'test2', '', '']
  </code></pre>
  
  <p>I am trying to find a way to replace character u which is before 'test1' and 'test2' with none ''. So after replacing it will look like:</p>
  
  <pre><code>['test1','test2', '', '']
  </code></pre>
  
  <p>Initially I had list like following:</p>
  
  <pre><code>[u'test1\n', u'test2\r\n', '', '']
  </code></pre>
  
  <p>This I could reduce using following:</p>
  
  <pre><code>row_val = [w.replace('\n', '') for w in row_val]
  row_val = [w.replace('\r', '') for w in row_val]
  </code></pre>
  
  <p>Let me know there is a way to perform the same without iterating through each string.</p>
