If you have simplejson  ( http://cheeseshop.python.org/pypi/simplejson
) installed you can do
mydict = simplejson.loads( mystring )
but in this case all occurances of 'None' in your string should be 'null'.

Or if you absolutely trust the string to contain nothing dangerous:
exec( 'mydict = %s' % mystring )
