You will see this in the list archives several times in the past.
Depending on the object, id is a method and not an simple attribute.

To be on the save side (instead of figuring out what it is actually)
always use: getId()

Btw. <dtml-var id> does not use the id the same way like 
<dtml-if "id==last">. Try <dtml-var "id"> and you will see
the method signature (view document source in the browser)

I'd recommend doing that all in a python script and then
use the prepared data in your DTML - oder later ZPT.
