title: Execute shell command from python script (RaspberryPi)
body: <p>I am trying to execute this command <code>sudo mavproxy.py</code> from a python script on raspberrypi. I can execute this in the shell and see it load. </p>
  
  <p>The code i have for my current test is:</p>
  
  <pre><code>import subprocess
  subprocess.call('sudo mavproxy.py')
  </code></pre>
  
  <p>running this the code executes however looking at the terminal window nothing happens. So i'm not sure whether it is executing correctly. Any help would be greatly appreciated.</p>
