How do you update label text in Python Tkinter (Python, TkInter, development)?

By /

The Tkinter library in Python provides various widgets that can be used to create graphical user interfaces (GUIs). One of the most basic widgets is the Label widget, which allows you to display text or images on a window.

Here’s an example of how you can create a simple Tkinter window with a label widget:

import tkinter as tk

# Create the main window
window = tk.Tk()

# Create a label widget
label = tk.Label(window, text="Hello, Tkinter!")

# Pack the label widget to add it to the window
label.pack()

# Start the Tkinter event loop
window.mainloop()

How do you update label text in Python Tkinter (Python, TkInter, development)?

To update the label text in Python Tkinter, you can follow these steps:

  1. Create a Tkinter label widget using the Label class.
  2. Store the label widget in a variable.
  3. Use the config method of the label widget to update the text property.

Here’s an example code snippet that demonstrates how to update the label text dynamically:

import tkinter as tk

def update_label():
    new_text = "New Text"
    label.config(text=new_text)

root = tk.Tk()

# Create a label widget
label = tk.Label(root, text="Initial Text")
label.pack()

# Create a button to update the label text
button = tk.Button(root, text="Update", command=update_label)
button.pack()

root.mainloop()

In this example, we define a function update_label that sets a new text value and updates the label using the config method. We create a button that calls this function when clicked. When the button is clicked, the label text will be updated with the new text
