Hi all, I am building a graph to create a drawing transmittal: [image] The difficulty comes when I have to rearrange the data extrated from the sheets: [image] Here my two questions: How to add an element to a list to make sure each sublist has as many elements as revisions (in my example ea…

SOLVED!!! [image] The Blue group renumbers the Revision Sequence with consecutive numbers and applies it to the Revision Sequence on sheets. Then I can use @Dimitar_Venkov ’s code normally. Again, thanks all for your help!

Hi Pablo I suggest using Dynamo to extract the data, then something with a PIVOT function- such as Excel to present it in this format. You could probably come up with a solution in Dynamo, although it might not be pretty Andrew

Hi Andrew, that is what I currently have :slight_smile: I was wondering if I could achieve the same result directly from Dynamo but that additional step is adding more complexity that I can handle.

Can you sketch what your final result would look like?

Hi Salvatore, The result would look like this: [image] Then I can write that List of Sublist in Excel so it’ll look as the first image of my post. Thanks!

@Pablo_Perez_Valdivia Well, we always like a good challenge :slight_smile: This is my solution in Python: [image] Rev=IN[0] Ind=IN[1] import sys pyt_path = r'C:\Program Files (x86)\IronPython 2.7\Lib' sys.path.append(pyt_path) import itertools def MapList(lst): return map(lambda x:x-1, lst) …

I think I’ve shown how to do recursive replacement with DS before, but can’t seem to find the example. You can try this: [image] def replace1(a:var[], i:var[], v:var[]){ return = [Imperative]{ for (x in GetKeys(i) ) { a[i[x] - 1] = v[x]; } return = a; }};

Thanks Salvatore! The more I see coding, the more I want lo learn. Can you recommend me any guide,course,tutorial… to start learning Python?

Bravo @Dimitar_Venkov , so neat! It works really well. I’ll add soon a extra layer of complexity that I just come across.

Look here: [image] Learning Python basics in Dynamo Developers Hi All, i’m trying to expand my knowledge of Dynamo with the power of Python. Does anyone know of a good starting point for learning the basics of Python, within the Dynamo workflow? [image…

Hi @Dimitar_Venkov , I have tested your code in a real case where the Revisions Sequence aren’t consecutive numbers as follows: [image] We have just 3 Revision Sequence: 9, 12, 17. As these are numbers, when I apply your code, the result is not the desired: 5 sublist with 3 elements in each. [i…
