How can separate text block in Python application?

Question

I'm learning Python and writing an application that should show text blocks on the screen. I'm using the tkinter library.

Text in some blocks may not fit in one line, so I've decided to use Text widget because it has the option of wrapping text. And I've also used Scrollbar widget because text blocks may not fit the screen. So my code looks like this:

root = Tk()
scrollbar = Scrollbar(root)
t = Text(root, wrap=WORD)

def show_messages():
    for i in range (0, len(messages)):
         t.insert(END, messages[i] + '\n')

def show_windows():
    scrollbar.pack(side="right", fill="y", expand=False)
    t.pack(side="left", fill="both", expand=True)
    root.mainloop()

show_messages()
show_window() 

And, after all, the messages should be separated with some kind of line, but I'm stuck on this. So, my question is: how can I separate my text blocks? Or maybe I'm going down the wrong path, and I should use Listbox widget instead of Text? Thanks in advance!

You can do it by inserting a black frame using the window_create method of the Text widget:

import tkinter as tk

root = tk.Tk()
scrollbar = tk.Scrollbar(root)
t = tk.Text(root, wrap="word")

messages = [
"""
#############################
#                           #
#       text block 1        #
#                           #
#############################
""",
"""
#############################
#                           #
#       text block 2        #
#                           #
#############################
"""
]

def show_messages():
    for i in range (0, len(messages)):
         t.insert("end", messages[i] + '\n')
         # add a black centered the text block
         f = tk.Frame(t, width=200, height=1, background="black")
         t.window_create("end", window=f)
         t.insert("end",'\n')

def show_windows():
    scrollbar.pack(side="right", fill="y", expand=False)
    t.pack(side="left", fill="both", expand=True)
    root.mainloop()

show_messages()
show_windows()
