[Zope-dev] Test to see if an item is a list

[Jason Spisak]

Actually with the purpose I have in mind, I have to use the klunky notation
because I am nesting sequences.  I new there was a reason that I passed
over that simple explanation.

BTW to test for a list I used try/except in DTML one line

    <dtml-try "REQUEST.form.values()[a][2]">

or in your other case

    <dtml-try "_['sequence-item'][2]">

If it can slice then it's a list or dictionary, and since DTML properties
can only store strings, integers, flots, text and lists (tokens/lines),
then that works for passing previous inputs from forms.

All my best,
