title: Macports Port Select Commands
body: <p>What are the new commands &amp; or equivalents of:</p>
  
  <pre><code>python_select -L (shows available python versions)
  
  python_select -s (sets the default version of your choice of python).
  </code></pre>
  
  <p>I know they have changed to <code>--list</code>, <code>--set</code>, <code>--show</code> but there doesn't seem to be an example of how to properly use each one. For example, if I use <code>port select --set</code> I get the following: </p>
  
  <blockquote>
    <p>Error: port select [--list |--set |--show]  []. </p>
  </blockquote>
