This is my first time using a two column array.

I think I’ve successfully built an array where the first column is one actor, and the second column is a related actor.  Now I want to loop through the list and set the parent of the first actor to the second actor. 

But I don’t know what the syntax would be to refer to the two columns of my list.

Something like this:

ActorList =[]

ActorList.append ([actor1,actor2])

…

For EachActor in ActorList:

actor1.SetParent(actor2)  ----- of course that is not the right syntax, what would be?

This should work

ActorList=[(1,2),(3,4)] actor=ActorList[0][0]

actor.SetParent(ActorList[0][1])

or

ActorList[0][0].SetParent(ActorList[0][1])

Thanks, Struct.

That's very close to what I read online but not quite an answer to my question. Your answer assumes that I know I am on row 0 and I know how many rows there are. I won't. I want to loop.

my question is:

During a looping process how can I refer to the CURRENT row, column 1 and 2?

maybe its: 

For EachActor in ActorList:

    [EachActor].[0]SetParent([EachActor].[1])

Yes that would work
except your point is in the wrong place.

for EachActor in list:

    EachActor[0].SetParent(EachActor[1])

Ah, and no brackets around EachActor got it,

(I was using SQL bracketing [table].[field])

I always go for less typing. The iterator can split your pairs for you.

for a, b in yourlist:

   a.SetParent(b)

Note:
If you were starting with two separate lists to begin with, you can skip making the list of pairs. The built-in function "zip" will iterate over two or more lists, giving you parallel elements from each - kind of like a zipper bringing the teeth from the two sides together.

for p, c in zip(listOfParents, listOfChildren):

    p.SetParent(c)

Thanks BB, I will have to remember that.
