In this article we will see how to create round radio button. By default the shape of radio button is rectangular although if we set width equal to the height it become square. Below is the representation of normal bordered radio button vs the radio button round in shape.

In order to do this we have to do the following :
1. Create a radio button.
2. Set its width equal to height to make it square
3. Add border to it with the help ofsetStyleSheetmethod.
4. Set border radius to half of width.
Style sheet code to do this –
QRadioButton
{
border : 3px solid black;
border-radius : 60px;
}
Below is the implementation.
# importing libraries from PyQt5.QtWidgets import * from PyQt5 import QtCore, QtGui from PyQt5.QtGui import * from PyQt5.QtCore import * import sys     class Window(QMainWindow):       def __init__(self):         super().__init__()           # setting title         self.setWindowTitle("Python ")           # setting geometry         self.setGeometry(100, 100, 600, 400)           # calling method         self.UiComponents()           # showing all the widgets         self.show()       # method for widgets     def UiComponents(self):           # creating a radio button         self.radio_button = QRadioButton(self)           # setting geometry of radio button         self.radio_button.setGeometry(200, 150, 120, 120)           # setting text to radio button         self.radio_button.setText("Radio Button")           # changing style sheet code of radio button setting border to         # radio button and changing radius to half of width         self.radio_button.setStyleSheet("QRadioButton"                                        "{"                                        "border : 3px solid black;"                                        "border-radius : 60px;"                                        "}")     # create pyqt5 app App = QApplication(sys.argv)   # create the instance of our Window window = Window()   # start the app sys.exit(App.exec())  | 
Output :
