JSON is in fact a subset of JavaScript, and modern browsers now include a specific API for parsing and generating it (https://developer.mozilla.org/En/Using_native_JSON ). Python likewise has a JSON module in the std lib: http://docs.python.org/library/json.html > OR > 2) >>> import array >>> y =3D array.array(i, L) > =C2=A0then return y to javascript function > But the problem with this method is, it will give an array of basic value= s > only. The word "array" gets tossed around a lot by programmers. The `array` module is not at all what you want in this case. Cheers, Chris -- http://rebertia.com
