Split multiple Lines by Points

Hello, how are you? Good afternoon everyone, again I am struggling with Python within Dynamo
So I wanted to see if any of you can support me

I want to evaluate if a point intersects the line or not and I want to create a dictionary with the points that intersect the line, now I am creating the definition but my question is how I could make these sublists within a general list
My goal is to create a list with the points that intersect the line and then apply the splitCurves.By Points function.

Could you guide me a bit on how to do the syntax to achieve this, I am new to Python and it is difficult for me to change the nodes for the code.

This is the Code
# Load the Python Standard and DesignScript Libraries
import sys
import clr
clr.AddReference(‘ProtoGeometry’)
from Autodesk.DesignScript.Geometry import *

clr.AddReference('DSCoreNodes')
from DSCore import *

# The inputs to this node will be stored as a list in the IN variables.
Curves = IN[0]
Points = IN[1]

#Obtain the Exterior Columns
def SplitByPoints(Curves,Points):
	Count= 0
	EvList=[]
	for Curve in Curves:
		for Point in Points:
			Ev= Curve.DoesIntersect(Points)
			if Ev:
				Ev.append([Count]EvList)
	Count =+ 1
	return EvList


# Assign your output to the OUT variable.
OUT = 0

This is the context

Why do you intersect points and not Single point in the loop?

This is the simple way to show the problem, in the real problem the list are not vinculate with each other so the problem can’t solve usign that aproach

I show the code how to solve this problem. Gustavo Gonzales was the friend that solved this problem, thank you very much to help me.

# Load the Python Standard and DesignScript Libraries
import sys
import clr
clr.AddReference('ProtoGeometry')
from Autodesk.DesignScript.Geometry import *

clr.AddReference('DSCoreNodes')
from DSCore import *

# The inputs to this node will be stored as a list in the IN variables.
Curves = IN[0]
Points = IN[1]

diccionario = {}

for Curve in Curves:
	diccionario[str(Curve)] = []
	

#Obtain the Exterior Columns
def SplitByPoints(Curves,Points):
	Count= 0
	EvList=[]
	curves = []
	for Curve in Curves:
		for Point in Points:
			if Curve.DoesIntersect(Point):
				Count += 1
				diccionario[str(Curve)].append(Point)
	for curve1 in diccionario.keys():
		for curve2 in Curves:
			if curve1 == str(curve2):
				curves.append(curve2.SplitByPoints(diccionario[curve1]))
	return curves
		
# Assign your output to the OUT variable.
OUT = SplitByPoints(Curves,Points)
