title: Calling Python from JavaScript
body: <p>Is there a simple way to call Python libraries from JavaScript? Especially from the inside of a Firefox extension.</p>
  
  <p>A good option to compile a pure Python library would also be great. I looked at <a href="http://en.wikipedia.org/wiki/Pyjamas_(software)" rel="noreferrer">Pyjamas</a>, but it seems to offer only partial support for Python.</p>
