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. That's because, in your example, each time through the loop, single is an int. Try indexing m instead. I think all thats needed is a tal:condition (he wants to filter out rows) 1)<span tal:define="res python: context.pyTest();"   <--- returns list of lists  like [[61282125371L, 1, 6, 0], [61282125379L, 1, 6, 0], [61282825240L, 6, 6, 0]]                 tal:repeat="r1 res"> 3)    <tal:span tal:repeat = "r2 r1" 4)        tal:condition="python: repeat.r2.number in (1,2,4)" 5)        tal:content="r2"> 6) </tal:span> Where 4 is not brain dead as in my example.
