Create a numbering sequence for key repeated values in a List

[tiagoricotta]

Hi guys,

I have a list with some key values that repeats and I want to substitute the key value by a numbering sequence of each key:

I was able to get all information but I cannot figure out how to make the List.Map values have the information that I need (1,2,1,2,3,4,5,6,7,8,9,10,11,3,4,1,2…etc)…

Any help here?

A screenhot clearly indicating the initial and expected lists could be useful. You can check first what’s already available on this topic and start to experiment from that, see for example:

• http://dynamoprimer.com/en/06_Designing-with-Lists/6-3_lists-of-lists.html
• Dynamo Dictionary
• Enjoy Revit: Examples for All List Actions in DYNAMO
• Managing Lists in Dynamo – landarchBIM
• See also if existing discussions can’t help, such as this one for instance:

Matching sublist elements sequentially

It seems that the OOTB nodes can’t do this easily. These ones could help: [List-replace-items]
