Okay, I seem to be having a real brain moment. Given two inputs, which are equal length lists (of varying internal length), how can I do a dict/zip type operation in the GhPython component whereby one input is going to be a dictionary key, and one is going to be a value? In the below case, a list o…

[image] Jonathan Hutchinson: The grasshopper implicit cycle means that the some dictionary.update() has no purpose, right? Correct, in your case you will need to set the access type to tree and do something like this: [2023-01-21 09_45_52-] 230121_ToGHPythonDict_00.gh (13.4 KB) Edit: You …

My wish is to be able to use the list of names as keys, and the associated list of points as values, in a python dictionary which could then be written into a JSON file of keys and values. From my search so far, I am seeing a few possible routes and patterns emerging around ghpythonlib.treehelpers …

[image] Jonathan Hutchinson: I feel like I am missing something Me too. You didn’t mention Python and I see no effort at it in your GH file. [image] Jonathan Hutchinson: What I’m gathering so far is that dictionaries don’t seem to play too nicely in the ghpython component, unless I’m mi…

[image] Jonathan Hutchinson: GhPython and the subtopic also :slight_smile: thank you for your attempts, sorry you couldn’t offer the solution.

[image] Jonathan Hutchinson: a real brain moment Well … that’s a classic - simple - puzzle addressed (general case) as follows: Data: A custom Object collection is required (where Object is an entity build via a Class). Define suitable Properties related with something (that could be flat…

Perfection. Very helpful, Anders. 6 months-ish without opening Grasshopper has really taken its toll. It looks like the rule of thumb, then, is that if I want to treat things ‘statically’ I need to do this input node trees >>> regular python types conversion. It looks like I will need to take a lot …

[image] Jonathan Hutchinson: It looks like the rule of thumb, then, is that if I want to treat things ‘statically’ I need to do this input node trees >>> regular python types conversion. It really depends on the case. But a good GHPython rule of thumb is to treat lists as lists and trees as t…

[image] AndersDeleuran: I should have been more precise, my bad. No problem at all. This was a really good, concise and to the point solution. I made the mistake of feeling that the structure I had to begin with, a (kinda) list and (kinda) list of lists would get me where I needed. In the end…
