Listbox Tkinter | Python 3

In this tutorial, we are going to see how to use Listbox in Tkinter. The Listbox widget allows to show a list of elements from which a user can select a number of elements.
 

 
 

Syntax:

Here is the syntax to create this widget:

liste = Listbox ( master, option = value, ... )

 

Parameters:

• master : This represents the parent window.
• options : See below for a list of the most commonly used options for this widget. These options can be used as comma separated key-value pairs.

 

Example:

from tkinter import *

gui = Tk()

list = Listbox(gui)
list.insert(1, "Blue")
list.insert(2, "Red")
list.insert(3, "Green")
list.insert(4, "Yellow")
list.insert(5, "Orange")
list.insert(6, "Black")

liste.pack()
gui.mainloop()

Output:
