[Zope] List within a list - how to use in a page template

[Cameron Beattie]

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.
