You might want to not use ZGadfly, it have a feeling it doesnt store data
between reboots...

<dtml-call pythonScript> or since you passing through data and wanting the
python script to print stuff
<dtml-var "pythonScript(list=the_list)">, you will need specify list as an
argument in your python method.

Preferably do it in python and as little as possible in dtml.

<dtml-in list_one>
   <dtml-in "_['sequence-item']">
     <dtml-var sequence-item>
   </dtml-in>
</dtml-in>

Or something like that.

Thanks.
