How can I change the text of the Tkinter Listbox item?

To display a list of items in the application, Tkinter provides a Listbox widget. It is used to create a list of items vertically. When we want to change the text a specific Listbox item, then we have to first select the item by iterating over the listbox.curselection() and insert a new item after deletion. To insert a item in the list, you can use listbox.insert(**items).


# Import the required libraries
from tkinter import *
from tkinter import ttk

# Create an instance of tkinter frame or window

# Set the size of the window

# Create a Listbox widget
lb.pack(expand=True, fill=BOTH)

# Define a function to edit the listbox ite
def edit():
   for item in lb.curselection():
      lb.insert("end", "foo")

# Add items in the Listbox

# Add a Button To Edit and Delete the Listbox Item
ttk.Button(win, text="Edit", command=edit).pack()



Executing the above code will display a window that contains a list of items.

Now, select an item from the list and click "Edit". It will edit the selected item in the list.
