For loop - adding diferent sublists

DesignScript
1

Hello,
I’m quite new in programming (at all levels). I’m trying to jump from nodes to DesignScript to improve some of my scripts.

I’m getting stuck with a simple for loop (I think, but my level it is what it is) and I don’t get how to get around this.

I’m trying to simplify this definition with for loop:

list1= [[“a”,“d”],[“b”,“e”],[“c”,“f”]];
list1[0];
nestedList1=[
(list1[0]<1>+list1[1]),
(list1[0]<1>+list1[2])
];

nestedList2=[
(list1[1]<1>+list1[2])
];

DSCore.List.Flatten([nestedList1,nestedList2]);

What I’m trying to do, it’s simplifying that code with a for loop, but there is something that maybe I’m not understanding in the way of getting the results from the for loop.

list1= [[“a”,“d”],[“b”,“e”],[“c”,“f”]];
iListCount = DSCore.List.Count(list1@L2) -1;
iList=iListCount-1;

[Imperative]
{
result = ;
for (i in 0…iList)
{
result = (list1[i]<1>) + (list1[i+1…iListCount]);
}
return = result;
};

When I finish this code I get an error: Imperative factor not valid.
I didn’t used the flatten here, because I couldn’t get further before getting the result in sublists.

Probably it’s a silly issue that I’m not considering or I haven’t understood correctly in the data list structure.

I hope someone can help me to get across this little rock.

Thank you in advance.

first thing is that you cannot use replication or replication guides inside an imperative block.

Thank you, didn’t noticed about replication and levels in imperative.

Just accomplished with this code:

list1= [[“a”,“d”],[“b”,“e”],[“c”,“f”]];
iListCount = DSCore.List.Count(list1@L2) -1;
iList=iListCount-1;

resultEnd=[Imperative]
{

  • result = ;*
  • for (i in 0…iList)*
  •   {*

  •   for (j in 0..iList)*

  •   	{*

  •   	result[i][j] = [list1[i][j] + list1[i+1][j],list1[i][j]+list1[i+1][j-1],list1[i][j] + list1[i+2][j],list1[i][j]+list1[i+2][j-1]];*

  •   	}*

  •   }*

return = result;
};
flatList=DSCore.List.Flatten(resultEnd);
mask=flatList@L1==null;
endList=DSCore.List.FilterByBoolMask(flatList,mask);
endList[“out”];
DSCore.List.Sort(endList[“out”]);
