Radio buttons are a type of widget that allows the user to select one option from a set. In this example, we will create a form with two radio buttons and a text field.
The first step is to create the form. We will do this in the main() function. The form will have the following layout:
The first radio button will be for selecting a color, the second radio button will be for selecting a shape, and the text field will be for entering a message.
Next, we will create the RadioButton widgets. We will do this in the create_widgets() function. The first radio button will have the following code:
The second radio button will have the following code:
The text field will have the following code:
Finally, we will run the main() function. When the user clicks on the radio buttons, the selected value will be stored in the variable. The text field will display the message entered by the user.

Radio buttons are a type of widget used in graphical user interfaces. They allow the user to choose one option from a set of options.
In Tkinter, a radio button is created using the RadioButton() constructor. The constructor takes two arguments: the text displayed on the button and the name of the variable to store the value of the button in.
To create a group of radio buttons, you can use the Group() constructor. This constructor takes two arguments: the text displayed on the group box and the name of the variable to store the value of the group in.
When a user clicks on a radio button, the button’s value is stored in the variable associated with it. If a user clicks on a radio button in a group, the value of the group is stored in the variable associated with the group.
Radio button is a graphical control element that allows the user to choose only one of a limited number of mutually exclusive options. Radio buttons are displayed as small circles that are either filled in or not. When selected, a radio button will have a border around it.
Radio buttons are commonly used in forms to allow the user to make a selection. For example, a form might ask the user to indicate their gender by selecting one of the following radio buttons:
Male
Female
Radio buttons can also be used in pairs to allow the user to make a choice between two options. For example, a form might ask the user to indicate their age group by selecting one of the following radio buttons:
Under 18
18-25
26-35
36-45
46-55
56+
Radio buttons can also be used in groups. For example, a form might ask the user to indicate their country of residence by selecting one of the following radio buttons:
Australia
Canada
France
Germany
Italy
Japan
Mexico
Spain
United Kingdom
Radio buttons can also be used to provide feedback. For example, a form might ask the user to indicate their gender by selecting one of the following radio buttons:
Male
Female
If the user selects Male, the form might then provide feedback by saying “Thank you for your selection. Male is selected.”
Radio buttons are one of the most commonly used widgets in Tkinter. They are used to allow the user to select one option from a group of options.
When you create a radio button widget, you must specify the name of the button. This is the name that you will use to refer to the button in your program.
When you create a group of radio buttons, you must give each button a different name.
When you create a group of radio buttons, all of the buttons are initially selected.
You can use the select() method to select a specific button in a group of radio buttons.
You can use the deselect() method to deselect a specific button in a group of radio buttons.
Radio buttons are graphical elements used in forms to allow the user to select one option from a set of mutually exclusive options. In Python, you can interact with radio buttons by using the functions provided by the tkinter module.
The following code creates a simple window with a single radio button:
window = tk.Tk()
radio = tk.RadioButton(window, text=”Please select one option”)
radio.pack()
When the user clicks on the radio button, the Python interpreter will execute the code associated with the button. You can specify the code to be executed by setting the button’s command attribute.
For example, the following code will display a message when the user clicks on the radio button:
radio.command = “print(‘You selected the option %s.’)” % radio.get()
You can also use the RadioButton class to create groups of radio buttons. The following code creates a window with two groups of radio buttons, each with three options:
window = tk.Tk()
group1 = tk.RadioButtonGroup(window, text=”Male”)
group1.add(tk.RadioButton(window, text=”Male”))
group1.add(tk.RadioButton(window, text=”Male”))
group2 = tk.RadioButtonGroup(window, text=”Female”)
group2.add(tk.RadioButton(window, text=”Female”))
group2.add(tk.RadioButton(window, text=”Female”))
radio1 = tk.RadioButton(window, text=”Male”)
group1.add(radio1)
radio2 = tk.RadioButton(window, text=”Female”)
group2.add(radio2)
window.mainloop()
What is IntVar () in Tkinter?
IntVar is an abbreviation for Integer Variable. It is a data type that stores integer numbers. IntVar objects are created by the IntVar() function.
How do I make a checkbox in Python?
A checkbox is a type of input field that allows a user to select a single item from a list of options. In Python, you can create a checkbox field with the input() function.
To create a checkbox, you first need to create a list of options. The options can be any valid Python data type, including strings, numbers, and lists. You can then use the input() function to create a checkbox field that displays the options to the user.
The input() function takes two arguments: the name of the field and the list of options. Here is an example:
name = input(“Please enter your name: “)
options = [‘Al’, ‘Bob’, ‘Cathy’, ‘Dave’]
print(“You entered: “, name, “with the following options: “, options)
The input() function will create a checkbox field that displays the options to the user. When the user clicks on the checkbox, the input() function will return the value of the selected option.
Can we create GUI using Python?
Yes, we can create GUIs using Python. GUI toolkits such as wxPython, PyQt, and Tkinter provide a Python interface to the underlying GUI toolkit.
