Try looking at the total number of objects being combined into a string. If it’s more than 3 include “AND”. You can do this by replacing the final substring or just including an extra condition in a python node.

Python Script:

# Charger les bibliothèques DesignScript et Standard Python
import sys
import clr
clr.AddReference('ProtoGeometry')
from Autodesk.DesignScript.Geometry import *

# Les entrées effectuées dans ce noeud sont stockées sous forme de liste dans les variables IN.
_list=IN[0]
# Placer votre code au-dessous de cette ligne
cont=[]
for i in (IN[0]):
    if len(i)==1:
        cont.append([i[0]])
    if len(i)==2:
        cont.append([i[0]+" AND "+i[1]])
    if len(i)==3:
        cont.append([i[0]+", "+i[1]+" AND "+i[2]])           
# Affectez la sortie Ă  la variable OUT.
OUT = cont

If you want something scalable you can add conditional checks for the specific conditions you need met.

import sys
out = []

first_sep = ", "
second_sep = " and "

for lst in IN[0]:
    s = first_sep.join(lst)
    s = s[::-1].replace(first_sep[::-1], second_sep[::-1] , 1)[::-1]
    out.append(s)
    
OUT = out
