List.Contains with two lists of different lengths

Lists-Logic
1

I have two lists of different lengths. Both contain key values from the same list (curve list).

The list that contains 11 items is the result of seeing if a box intersects with a curve from the curve list.

The other list with 6 items is the keys from the curve list.

Now I want to compare the 6 item list to the 11 item list. If the value is not on the 11 item list I want to return false if it is I want to return true. (I have my desired output shown in picture.)

I’m thinking that I can use the ‘List.Contains’ node to go through each list, but I’m thinking that I’m not getting the lacing right.

I appreciate any help or direction.

I was able to figure out how to get 11 lists of 6 items so true or false for each of the 11 items.

But I really just want one 6 item list.

So a way to combine these or a better method to compare the two lists.

Again I appreciate any help or direction.

Try a combination of the == node set to cross product and the contains node.

Or if your going the other way just change the levels on your list.contains.

Or instead of Booleans.anytrue use List.AnyTrue from clockwork.

This node actually works correctly on its own. List Levels is making it worse. The inputs are to see if a list contains an item. It’s already expecting a list and a singleton so if you supply a list and a list it will iterate through the item list automatically.

This works.

Thank you. I did not have this package installed.

Oddly though I had to switch the inputs around. I tried it the way you show with shortest lacing and I end up with a list of lists. If I flip the inputs and keep lacing at Auto I end up with the results you show.
