title: Splitting a list into a string
body: <p>This is my list:</p>
  
  <pre><code>animals = ['dog', 'cat', 'mouse']
  </code></pre>
  
  <p>I want to split it so I end up with a string with the three strings inside the list, like this:</p>
  
  <pre><code>dog/cat/mouse
  </code></pre>
  
  <p>I have tried using the following code, but it just prints the original list:</p>
  
  <pre><code>print [e.split('/')[0] for e in animals]
  </code></pre>
  
  <p>Anything wrong?</p>
