title: Remove empty strings from a list of strings
body: <p>I want to remove all empty strings from a list of strings in python.</p>
  
  <p>My idea looks like this:</p>
  
  <pre><code>while '' in str_list:
      str_list.remove('')
  </code></pre>
  
  <p>Is there any more pythonic way to do this?</p>
