Example 1: integrate label into listbox tkinter

import tkinter as tk # python3
root = tk.Tk()
myList = tk.Listbox(root)
myText = "A list item"
myList.insert(tk.END, myText)
myList.pack()
lbl = tk.Label(myList, text=myText, anchor="w", font=("Helvetica", "24"))
lbl.pack(side="top", fill="x", anchor="w")
root.mainloop()

from tkinter import *
from tkinter import messagebox

def listMessageBox(arr):
  window=Tk()
  listbox=Listbox(window)
  listbox.pack(fill=BOTH, expand=1) #adds listbox to window
  [listbox.insert(END, row) for row in arr] #one line for loop
  window.mainloop()
  
arr=['a','b','c','1','2','3']

listMessageBox(arr)
