IronPython Runtime List. ===> Problem.

Working on my Project of CSV Component i found a problem that i dont find solution in the Internet or in the previous Discussions.

i dont know why a list of suposed data in GH appears like a Iron Python Runtime List.

here's the Code and a image of that's happening .

Hi Toussaint,

Python Component cannot return lists of lists as an output. You should flatten the list, and then assign it to csvData... See Giulio's comment here.

If you want to have the lists separated you may want to use DataTrees and branch the data. Check this.

make data trees! It's the only way that grasshopper can support lists of lists


# for accesssing GH classes

import clr

clr.AddReference("Grasshopper")

from Grasshopper.Kernel.Data import GH_Path

from Grasshopper import DataTree

dataTree = DataTree[object]()

for i, thing in enumerate(data):

    branch_id = branch_ids[i]

    path = GH_Path(branch_id)

    dataTree.Add(thing, path)

a = dataTree

otra alternativa sería no usar split dentro del script, dejando cada linea como un "string" singular.

entonces, se puede usar el "split string" componente de Grasshopper para crear branches de los lists of lists.

el split lo tengo que utilizar obligatoriamente, porque necesito indexar cada una de la informacion de los strings para poder Sortear por campos

i guess that a DataTree coding explanation for dummies will be so helpfull
