[Zope] DTML question

[TFE MMS JARVIS JOHN]

 I was just having a problem with this myself and this solution worked
like a charm. Thank you!

 I'm still left with a question, though: How would you go about using
 sequence-item, etc. in a python expression? Python sees it as
 'sequence minus item' and I get a 'Name Error: sequence' exception.

I was wanting to do something like this:

<table>
  <!--#in "dictionary.keys()"-->
    <tr>
       <td><!--#var sequence-item--></tr>
       <td><!--#var "records[sequence-item]"--></td>
    </tr>
  <!--#/in--> 
</table>

Which seems natural to me but, of course, doesn't work.
I have the feeling that I might need this in something like 

<!--#if "sequence-item=='gotcha!'"-->Ouch!<!--#/if--> 

someday. I've read the DTML manual several times  but 
have I missed something here?
<!--#with sequence-item-->???

Again, Thank You!
