[image] Hi folks, referring to the upper image, is it possible to reach the green box result with the red box nodes? If not, why? What’s the logic behind? Thanks in advance

@Einar_Raknes @Carlo_Beltracchi String.Join and String.Concat are based off of the .net class, string. The .net class has several overloads for both Join and Concat. [image] [image] Depending on what arguments you feed into the nodes, the system makes its best guess as to what you want to happe…

Many thanks @viktor_kuzev ! :slight_smile:

@Carlo_Beltracchi I’ve been wondering about that too! String.Join and String.Concat handles lists different than all the other nodes. We are expecting combined lists as default behavior, Maybe somebody in dev. team have an explanation? @Zach_Kron @Racel With that said, the equivalent node to the co…

[image] @Einar_Raknes , thanks for your answer. In my opinion the key is the need of adding an empty string inside the string Concat node…maybe this let you get a sort of “empty slot”. I think it depends from combinator (or function) logic…

Yes I understand how that works. The empty slot makes the String.Join node header grey and that means that the node has turned into a funcition f(x) with the empty slot as a variable x. The input of List.Map is that function f(x) and a list of x values. I was just wondering why List.Join and List.C…

Maybe this blog post can give a little help. [image] Dynamo - List Processing Many Dynamo layouts need to process lists. Lacing is one option, and recursion is another, but sometimes the built-in list-processing nodes ...

Very descriptive! Solved my case! Kudos Racel :smiley:

hi, do we have a workflow to join any number of words in a list with space as a separator without using string.join (with separator). Because if we do not know number of words so we cannot ++++ string 1,2,3 and join them. Thanks, ap
