Have your method return a dictionary instead of a list of tuples. Then you can directly access an item by its key. A tuple is not indexed except by position, so you can't jump into the middle by using a key. It's probably a non-issue, though. The length of your list would have to be pretty large for there to be a noticable delay because you have to look through the list. Still, a dictionary is what you want.

I was wondering if what I am trying to do is possible, or not.
I have a method that returns a list of tuple pairs eg:
[(firstname, Di), (lastname, van Dulken), (address, ...) ] etc.
I have no problem looping through this to get the sequence-item, sequence-key information:
<dtml-in "getDetails(_.None, _, status='Active')"> <dtml-in sequence-item> <dtml-var sequence-key> = <dtml-var sequence-item> </dtml-in> <hr> </dtml-in>
works fine.
BUT, I really only want (on this page, the method is used on other pages)
to
know a couple of the tuple details in the list. I know I can get this by looping through the whole sequence and using
<dtml-if "sequence-key == 'firstname'">
but that seems an incredibly slow and clunky way of referencing it to me. Is there anyway I can reference the tuple value by the tuple key without having to loop through them that way? I've tried getitem('firstname') and sequence-var-firstname, but neither of these work. I couldn't find any one else asking this, so I assume it is too basic for normal people to query on.
I also know I can reference THE tuple I am after by using sequence-item[1] (or whatever), but that rather removes the whole point of having name variables.
