While Python dictionaries are basically JSON syntax, there are some differences which would prevent you from loading the dictionary created in Python in JavaScript.

Among them, Python uses {{False}} while JavaScript uses {{false}}.  They are not interchangeable.

A good review of Python JSON libraries is at [http://deron.meranda.us/python/comparing_json_modules/].

I personally use [simplejson | http://code.google.com/p/simplejson/].
