I even looked through the code in DT_In.py and couldn't figure out where it handled this special case. This seems to me like a pretty big gotcha. I did find out that a list of two items was not handled the same way as a tuple of two items.

Well, the only solution I came up with was to iterate with an index over the size of the thing. -- cary ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

Re: [Zope] Arrg! dtml-in can't handle lists of pairs!
I have confirmed that this is strange behavior can be reproduced on 2.1.6 -- why I don't know. A work around may be to convert your tuples to lists (easy to do in python) sample working code: Iterate over 3.tuples Iterate Over 2-tuples Why can't I do this!
