Easily Master Radiobuttons in Python Tkinter GUI 🟢

Introduction:

In this tutorial, we will learn how to create a simple GUI application using Python’s tkinter library. Specifically, we will focus on creating radio buttons, which allow users to select one option from a group of options. Radio buttons are a common GUI element that can be used to present users with a set of choices and allow them to make a selection.

Prerequisites:
Before getting started with this tutorial, you should have basic knowledge of Python programming language and some familiarity with tkinter library. If you are new to tkinter, I recommend going through some introductory tutorials to get familiar with the basics of creating GUI applications using tkinter.

Step 1: Import the necessary modules
To get started, you will need to import the tkinter module and the tkinter’s messagebox module. You can do this by adding the following lines of code in your Python script:

import tkinter as tk
from tkinter import messagebox

Step 2: Create the main window
Next, create the main window for your application. You can do this by creating an instance of the tk.Tk class and assigning it to a variable, like so:

root = tk.Tk()
root.title(“Radio Buttons Tutorial”)

Step 3: Create the radio buttons
Now, let’s create some radio buttons for the user to choose from. You can create radio buttons by creating instances of the tk.Radiobutton class and passing the necessary parameters. In this example, we will create three radio buttons:

radio_var = tk.StringVar()
radio_var.set(“Option 1″)

radio_button1 = tk.Radiobutton(root, text=”Option 1″, variable=radio_var, value=”Option 1″)
radio_button2 = tk.Radiobutton(root, text=”Option 2″, variable=radio_var, value=”Option 2″)
radio_button3 = tk.Radiobutton(root, text=”Option 3″, variable=radio_var, value=”Option 3”)

radio_button1.pack()
radio_button2.pack()
radio_button3.pack()

Step 4: Create a function to display the selected option
Now, let’s create a function that will display a message box with the selected option when the user clicks a button. You can do this by creating a function like the one below:

def display_selected_option():
selected_option = radio_var.get()
messagebox.showinfo(“Selected Option”, f”You have selected: {selected_option}”)

Step 5: Create a button to trigger the function
Now, let’s create a button that will trigger the display_selected_option function when clicked. You can create a button by creating an instance of the tk.Button class and passing the necessary parameters:

btn = tk.Button(root, text=”Show Selected Option”, command=display_selected_option)
btn.pack()

Step 6: Run the main loop
Finally, run the main loop of the application by calling the mainloop() method on the root window:

root.mainloop()

Conclusion:
In this tutorial, we learned how to create radio buttons in a tkinter GUI application using Python. We created a simple application that allows users to select one option from a group of options using radio buttons. We also created a button that displays the selected option in a message box when clicked. I hope this tutorial was helpful in getting you started with tkinter GUI programming in Python.
