David Ok, its best to parse your list of lists in a python script. You pass a tuple (or array) of inclusionary index numbers. It will return the filtered list of lists The problem with the try I gave before is that *condition* is evaluated before *repeat* :-0 So ... # python script # input: a tuple named tup of index items to include in list of lists, eg (1,3) and the list of lists #example input: listoflists = [[61282125371L, 1, 6, 0], [61282125379L, 1, 6, 0], [61282825240L, 6, 6, 0]] #example tup: (1,3) ret = [] for i in range(len(listoflists)): if i in tup: ret.append(x[i]) return ret Then your ZPT is easy.

[Zope] List within a list - how to use in a page template
I am trying to get my head around representing a list in a page template. Assume the following list: m [[61282125371L, 1, 6, 0], [61282125379L, 1, 6, 0], [61282825240L, 6, 6, 0], [61282125378L, 1, 6, 0], [61282125374L, 1, 6, 0] m[0] [61282125371L, 1, 6, 0] m[0][0] 61282125371L i.e. m is a list where each member is itself a list. How do I get a page template to render a particular item? Assume a function getem returns the list. tal:block repeat=m python:here.getem() td tal:repeat=single m tal:content=single/td This code will produce four columns and five rows, with each populated by the list members. But what if I only want the first and third members in each case i.e. 2 columns and five rows? I thought it would be something like tal:content=python:single[0] but that gives me an unsubscriptable object error. Any suggestions would be appreciated.
