Here's something, a Python wrapper around the SeaMonkey Javascript interpreter... http://pypi.python.org/pypi/python-spidermonkey

You could also use XPCOM, say in XUL based apps like Firefox, Thunderbird or Komodo.

Many of these projects mentioned above are dead or dying, lacking activity and interest from author side. Interesting to follow how this area develops.

For the record, in era of plugin based implementations, KDE camp had an attempt to solve this with plugin and non-language specific way and created the Kross https://en.wikipedia.org/wiki/Kross_(software) - in my understanding it never took off even inside the community itself.

During this chicken and egg -problem time, javascript-based implementions are definately way to go. Maybe in the future we seee pure and clean, full Python support natively in browsers.

There's a bridge based on JavaScriptCore (from WebKit), but it's pretty incomplete: http://code.google.com/p/pyjscore/

If your just interested in sharing complex data types between javascript and python, check out jsonpickle. It wraps the standard Python JSON libraries, but has some smarts in serializing and deserializing Python classes and other data types.

Quite a few Google App Engine projects have used this library. Joose and FirePython both incorporate jsonpickle.
