[Zope] Debugging a python routine

[John Poltorak]

Can anyone suggest how I would go about debugging a Python routine like 
this through Zope?


     <span
tal:define="opts 
python:here.lib.parse_file(file=here.members,sepr=',',clone=1)">
       <tal:block repeat="opt opts">
          <li><a     tal:content="python:opt[1]"
               tal:attributes="href python:opt[0]"></a></li>
       </tal:block>
     </span>
