[Answer]-Django / python collections issue

You confused the server-side code with client-side code

For example,

the server-side code

from django.shortcut import render_to_response

name_map_handler(request, **kwargs):
    """
    some code to handler the ajax request
    """
    render_to_response('the_template_you_want_to_use.html', {'LANGEAGE_CODES': ['zh-hans', 'de'])

only the server-side variable that you decide to render can be use in the Django template. Just like the LANGAGE_CODES in my example.
