I want to get the index of the minimum and the second minimun and third minimum of a sub list.
So I have made this script which works well using a small list.
But as soon as I use a huge list (several thousands), it crashes…
Do you have any idea to make it more efficient ?
What is the next step in your process? Why do you need the indices and not just the values?
How about sorting list and then getting its 2nd and 3rd item by List.Slice?
If you need indices of the original list I’d then retrieve them with AllIndicesOf node:
It seems to be a bit shorter way to achieve what you want.
@Nick_Boyts
hi Nick, yes then i want the value, but first the item…
tkx for your script, that’s what i 'm looking for, but i can find the node “if equal return index” and my node list.takeitem don’t get any @ in it, how do I get it ?
Enable levels by clicking on the > to the right of the input.
Check out the list @ levels area of the dynamo primer for more info.

What version of dynamo are you on?
Can you upgrade? Well worth it. Most documentation will be behind a bit otherwise and you’re missing out on some awesome features.
In the meantime, try setting lacing to longest and/or cross product on the nodes with levels enabled.
If your end goal is the values you don’t necessarily need the indices. You could just sort the values themselves and take the first three values from each sublist.
@Nick_Boyts
in fact, I do need the indices first, what about the node “if equal return index” ?
Is it from a specific package ?
It’s from its own package. Just search for If Equal Return Index.
@Pierre_MARECHAL Possible with OOTB nodes too.
Though not sure if SortByKey worked the same way in 0.9.1
