title: How to pass values by ref in Python?
body: <p>Basically I am using the C++ API of an app, but there is no reference for its python access. One variable is passed by ref, like so:</p>
  
  <pre><code>GetPoint ( Point  &amp;p, Object obj )
  </code></pre>
  
  <p>so how can I translate to Python? Is there a pass by ref symbol?</p>
