[Zope] TAL Question: Iterating through a list

All: I'm scratching my head trying to figure out how to to iterate over a list using TAL. Here's the scenario: I am calling a python script which wraps around a ZSQL method and simply returns the result set. The set comes back as a list of dictionaries. I'm getting stuck because I can't figure out how to tell TAL to to 1) grab each item and 2) grab the value associated with each dictionary key. On a related note is there a way to call a ZSQL method directly through page templates? Thanks in advance, -steve snesbitt@cobaltgroup.com
