title: Find and replace string values in list
body: <p>I got this list:</p>
  <pre><code>words = ['how', 'much', 'is[br]', 'the', 'fish[br]', 'no', 'really']
  </code></pre>
  <p>What I would like is to replace <code>[br]</code> with some fantastic value similar to <code>&lt;br /&gt;</code> and thus getting a new list:</p>
  <pre><code>words = ['how', 'much', 'is&lt;br /&gt;', 'the', 'fish&lt;br /&gt;', 'no', 'really']
  </code></pre>
