PythonJS translates Python 3 to Javascript. You can install it with pip:

pip install pythonjs

You will also need a pythonjs.js grab it with the following command:

wget https://raw.github.com/PythonJS/PythonJS/master/pythonjs.js

You start playing with a minimal page like the following:

<script src="pythonjs.js"></script>
<script src="app.js"></script>

app.js must be generated with the pythonjs command:

pythonjs < app.py > app.js

A minimal app.py is:

print 'Héllo world!'
