In this tutorial, we are going to learn about listbox in Tkinter along with its features and methods followed by a working example.

What is Listbox in Tkinter?

The Listbox widget in Tkinter is used to provide multiple options confined as a list. The List can only contain text items. You can choose one or multiple choices from the list. The syntax of declaring a ListBox is:

listbox_tk = Listbox( window, features )

Listbox features and properties are:

1 bg Decides the background color of the widget

13 xscrollcommand Lets the user scroll the Listbox horizontally.

7 nearest(y) Returns the nearest index when you provide the given coordinate in the Listbox
8 see(index) Makes the index visible. 
9 size() Shows the total number of items present in the list. 
10 xview() This is used to make the widget horizontally scrollable.
