title: How to convert a str to a single element list in python
body: <p>I have a <code>str</code> variable: <code>var_1 = "hello"</code> , and I want to convert it to a single element <code>list</code>, I try this:</p>
  
  <pre><code>&gt;&gt;&gt; list(var_1)
  ['h', 'e', 'l', 'l', 'o']
  </code></pre>
  
  <p>which is not the <code>['hello']</code> that I want.</p>
  
  <p>How do I do that?</p>
