how to do it. only see up to the first 5 charactershttps://stackoverflow.com/questions/64097000/how-to-do-it-only-see-up-to-the-first-5-characters

isimler = ["1", "2", "3", "4", "5", "6", "7", "8", "9"]
isimler_ikili = []

for i in range(len(isimler)-1):
    isimler_ikili.append(isimler[i] + " " + isimler[i+1] + " " + isimler[i+2])

for i in isimler_ikili:
    print(i)

aaa , abc , bbc , cde ,

aaa , +aaa+ , abc , +abc+ , bbc , +bbc+ , cde , +cde+ ,

A simple loop should work in Python

from functools import reduce 
import operator
a_str="""aaa , abc , bbc , cde ,"""
reduce(operator.concat, [[i,'+'+i+'+'] for i in a_str.split(" ,") if i])
