Make a template tag.
http://www.djangoproject.com/documentation/templates_python/ , the
section 'Writing custom template tags'.
In a template tag library, you need to create a node class, a compile
function, and then register the compile function. Then use the load tag
to load up your template tag library.

Alternatively, the easy way to do this would be to use
template_decorators.py from the new-admin branch at
http://code.djangoproject.com/browser/django/branches/new-admin/django/core/template_decorators.py
Then in your case you can do:
@simple_tag
def lookup_name(names, item):
return names[item.type]
and in your template:
{% load my_template_library %}
{% lookup_name ITEM_NAMES item %}
Of course if ITEM_NAMES is a constant you could import it in the tag
library and not pass it as an argument.
I'll submit template_decorators.py as a separate ticket.
