title: Are Python commands suitable in Vim's visual mode?
body: <p>I have found the following command in AWK useful in Vim</p>
  
  <pre><code>:'&lt;,'&gt;!awk '{ print $2 }'
  </code></pre>
  
  <p>Python may also be useful in Vim.
  However, I have not found an useful command in Python for Vim's visual mode.</p>
  
  <p><strong>Which Python commands do you use in Vim</strong>?</p>
