How do I select an axis-point in a list?

I have a list of points, where each point has XYZ coordinates. Using a code block, how do I select (let’s say) an x-axis point of a list, as shown below?

Itm.X in a code block?

It comes out as null…

oh wait, its l[0].X, thanks!

The node equivalent i believe is called ‘‘Point.X’’ or you can use ‘‘deconstruct point’’
