algorithmic modeling for Rhino

Python basics. Working with point coordinates.

Hello, I am new to python/gh programing.I'm testing with a very small program, but it doesn't work as I expected. It processes each point three times, as you can see.

I suppose it must be some stupid mistake, but I have been searching for it and I've not been able to find a solution.
Could someone make me any suggestions?

Is nudos a list input? I think the loop is iterating over the coordinates in each point, rather than over the list of points as a whole. That explains why everything is times 3 (once for x, y and z).

No, is a Item input.

That is what David was saying: you need to set the "nudos" to "List Access".
And change the:

    xpunto = nudos.X

to:

    xpunto = n.X

I'm afraid that this change does not work
