It really makes not sense to me why would you require a second list (of indices) in order to sort one list of values.

You don’t, the [A] input is optional. If you only want to sort numbers, just use the [K] input alone.

[image] DavidRutten: You don’t, the [A] input is optional. If you only want to sort numbers, just use the [K] input alone. :rofl: I didn’t check that, I assumed I have to provide every time. So I struggled whether to use range or series

Uhm, David, It’s kind of the other way around than what I would need. [image] I need to sort the values not the indices. :slight_smile:

Yeah, plug your values into K, and they’ll be sorted. A is optional. If you need some other things to be sorted synchronously along with your values, then you use the A (B, C, …) inputs.

Will I then get the reordered indices?

No. I thought you didn’t care about any indices and just wanted your values sorted. If you need the index then I’m afraid you’ll have to provide a list of unsorted ones.

Check this thread about the usecase: [image] [Python] List processing algorithm out of ideas Grasshopper Developer for the practical case, Is there a way to find all lines with X==i, Y = 0 and Z = 0 and sum them up? RhinoCommon, Grasshopper?
