How to use use List.Sublist in list @3 level

[phconghien]

Hello everyone, i’m struggling with this list-logic, can anyone help me solve this problem. Thanks a lot .
P/s: i dont want to flat the list because it will change the nature of the problem.

Is this what you are looking for?

If so you should set your List.Sublists-Node to Auto instead of Longest (||/)

do you use python?

list = IN[0]

output = []
for i in IN[0]:
	temp3 = []
	for j in i:
		temp2 = []
		for k in range(len(j)-1):
			temp = j[k:k+2]
			temp2.append(temp)
		temp3.append(temp2)
	output.append(temp3)

OUT = output

someone would do in a better way? I am always bad in declaring variables and python structure

Thank you for your apply , but it’s not what i need, because it’s different between the structure of 2 list, please see this image below

Thank a lot , i haven’t use python before, but i’ll give it a try. Is it flexible for all case (more list in each level ) ?

OK, then just use “keep liststructure”
