How do I iterate over branches and sub-branches in a tree with python?

[ivelin.peychev]

When I try to treat the tree as a list and find out its length I get an error that it does not have an attribute length.

I think you might need to use the tree helper functions. This might help?

'Brep Topology' in GH Python?

This might help? https://developer.rhino3d.com/api/RhinoCommon/html/Methods_T_Rhino_Geometry_BrepFace.htm By way of example, here is a ghpython sample, (Rhino V6), the replicates the Native Brep Topology Component. [BrepTopologyKnockOff_GHpy] import Rhino from ghpythonlib import treehelpers as th FF1 = [] FE1 = [] EF1 = [] for f in x.Faces: FF1.append(f.AdjacentFaces()) FE1.append(f.AdjacentEdges()) for e1 in x.Edges: EF1.append(e1.AdjacentFaces()) FF = th.list_to_tr…

DataTrees have BranchCount and DataCount properties. There’s no Length property.

Yes, I try to use this but I could not fine a way to iterate over the number of branches.

David can you give me an example (could be csharp) iterate, say I have a tree {0,n} I want with code to extract the data from each branch.

e.g.: I have this tree

I successfully get this:

But how can I split back this tree into 4(or as many as they are) lists?

nvm,
I got it, thanks for your time @chanley, @DavidRutten.

it was simpler than I thought. just 5-6 lines of code
