List Create (With Strings)

[Bren]

Can your python code [1] also work with strings? @c.poupin

import sys
import clr
clr.AddReference('ProtoGeometry')
from Autodesk.DesignScript.Geometry import *

lst = IN[0]

def splitBySequence(lst):
	if lst:
		grouplst = [lst.pop(0)]
		for i in lst:
			if i -1 == grouplst[-1]:
				grouplst.append(i)
		lst = [i for i in lst if i not in grouplst]
		return [grouplst] + splitBySequence(lst)
	else:
		return []
	
OUT = splitBySequence(lst)

List Create

Hello here is a solution with Python [image] import sys import clr clr.AddReference('ProtoGeometry') from Autodesk.DesignScript.Geometry import * lst = IN[0] def splitBySequence(lst): if lst: grouplst = [lst.pop(0)] for i in lst: if i -1 == grouplst[-1]: grouplst.append(i) lst = [i for i in lst if i not in grouplst] return [grouplst] + splitBySequence(lst) else: return [] OUT = splitBySequence(lst)

That’s just not how strings work. Try converting the string to a number to compare and then convert back.

How can I convert a character to a integer in Python, and viceversa?

Works perfectly with what @Nick_Boyts suggested.

lst = map(lambda x: ord(x), IN[0])

def splitBySequence(lst):
	if lst:
		grouplst = [lst.pop(0)]
		for i in lst:
			if i -1 == grouplst[-1]:
				grouplst.append(i)
		lst = [i for i in lst if i not in grouplst]
		return [grouplst] + splitBySequence(lst)
	else:
		return []
	
OUT = map(lambda y: [chr(x) for x in y], splitBySequence(lst))
