Moving an item from a sublist into another one

[rosarixx]

Hi everybody,

I have a problem moving an item from a sublist to another. I saw in another topic that a procedure can be remove the item from the old position and insert it again in the new one. But I don’t know what I have to write in the code block to get the index I want to move.

For example I would like to move the item “b” from sublist 1 into sublist 0 at the index 1.

Thanks in advance for help.

Hi Salvatore,

thanks for your post, your code is very interesting, but it’s not exactly what I’m trying to do.
I would like to delete the item “b” from sublist 1 and add it in sublist 0 at position 1 for example, the resulting list should be this one:

I tried to apply the remove and insert nodes, but I don’t know what to write in the code block to get directly the index (or the indices) I want to remove:

I was only able to do this:

but I have to move a lot of items so this procedure is too long, and I think not efficient.

@rosarixx Try this one

def replace(lsta:var…)
{
lstb=List.AddItemToEnd(lsta[1], lsta);
lstb[0]=List.AddItemToFront(lstb[2][1],lstb[0]);
lstb[0]=Reorder(lstb[0],{1, 0, 2, 3});
lstb[1]=List.RemoveItemAtIndex(lstb[1],1);
return={lstb[0],lstb[1]};
};
replace(lsta);

Another way, should be fast:
