I want to get the grild from Column Location Mark?
example: 2(-2400)-7(2300) => list = [2,7]
2(2400)-7(-2300) => list = [2,7]
2(2400)-7(2300) => list = [2,7]
2-7(2300) => list = [2,7]
2(-2400)-7 => list = [2,7]
Where are you struggling?

ok, so you are able to get the location mark at all 
You’ll need a more flexible filter to get to the values you want since quite a few stringvalues are possible.
I’d say: regex
Still learning regex / python but I think you are looking for something like this.
# Enable Python support and load DesignScript library
import clr
clr.AddReference('ProtoGeometry')
from Autodesk.DesignScript.Geometry import *
import re
regex = re.compile("^([a-zA-Z0-9]*)(\(.*\))?-([a-zA-Z0-9]*)(\(.*\))?")
input = IN[0]
output = []
if not isinstance(input, list):
input = [input]
for i in input:
if re.match(regex, i):
ilist = []
t = re.findall(regex, i)
ilist.append(t[0][0])
ilist.append(t[0][2])
output.append(ilist)
else:
output.append("no match found")
OUT = output
