[Zope] [DTML] creating variables

[David Ascher]

I need to detect not only whether a list is empty (that's easy with the
#if tag for example), but also whether all of the elements in the list
have a property. In Python, one could do this with something like:

  empty = 1
  for element in theList:
    if not element.hidden: empty = 0
    print element
  if theList and not empty:
    print "no non-hidden elements"

What's the equivalent DTML?  Can one create a variable in DTML?

Can anyone tell I miss my Python when writing DTML? =)
