If getDicts returns a list of python dictionaries then you are going to 
require an outer loop (to run thru the list) and an inner loop (to run thru 
the keys of the current dictionary).  Something like this will get you going 
in the right direction:

<dtml-let dictList="getDicts">
    <dtml-in dictList prefix=aDict>
        <dtml-in "aDict_item.keys()">
            <dtml-var sequence-item>, <dtml-var 
"aDict_item[_['sequence-item']]">
        </dtml-in>
    </dtml-in>
 </dtml-let>


However, it would be much easier to change your getDicts routine to format 
the data you need for your OPTION statements, instead of extracting this 
information via dtml.
