Grasshopper Python - BrachCount

[ForestOwl]

I found a former post of yours which relates to my question.

@AndersDeleuran

You can instantiate a DataTree and append Python lists to it like so (you can specify a datatype instead of [object]):

import Grasshopper as gh

def listToTree(nestedList):
    
    """ Convert a nested python iterable to a datatree """
    
    dt = gh.DataTree[object]()
    for i,l in enumerate(nestedList):
        dt.AddRange(l,gh.Kernel.Data.GH_Path(i))
        
    return dt

Giulio wrote some handy functions for reading/writing arbitrarily nested Python lists to DataTrees. I believe these come included with the Rhino WIP GHPython component.

That one helped me a lot.

I have a question about workflows. People do not usually work in Python with ‘braches and trees,’ people only use it for input or output translations. Is that correct?
