PyQt5 QRadioButton

Radio button has a circular shape and used when one choice is to be selected from multiple options. This button is in the selected state when the circle is filled and deselected when the circle is hollow. QRadioButton class is used to add a radio button in an application.

Example:
A window asking the user to select user’s gender. According to the user’s choice, it shows a message: “You are male/female” and which will change if the user changes his/her selection.
Below is the code:

Python3

import sys
from PyQt5 import QtCore, QtGui, QtWidgets

class Ui_MainWindow(object):
    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(466, 299)
        self.centralwidget = QtWidgets.QWidget(MainWindow)

        # Radio button for male
        self.radioButton_male = QtWidgets.QRadioButton(self.centralwidget)
        self.radioButton_male.setGeometry(QtCore.QRect(180, 120, 95, 20))

        # adding signal and slot
        self.radioButton_male.toggled.connect(self.maleselected)

        # Radio button for female
        self.radioButton_female = QtWidgets.QRadioButton(self.centralwidget)
        self.radioButton_female.setGeometry(QtCore.QRect(180, 150, 95, 20))

        # adding signal and slot
        self.radioButton_female.toggled.connect(self.femaleselected)

        self.label = QtWidgets.QLabel(self.centralwidget)
        self.label.setGeometry(QtCore.QRect(170, 90, 211, 20))
        MainWindow.setCentralWidget(self.centralwidget)

        self.retranslateUi(MainWindow)
        QtCore.QMetaObject.connectSlotsByName(MainWindow)

    def maleselected(self, selected):
        if selected:
            self.label.setText("You are male")

    def femaleselected(self, selected):
        if selected:
            self.label.setText("You are female")

    def retranslateUi(self, MainWindow):
        _translate = QtCore.QCoreApplication.translate

        MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
        self.radioButton_male.setText(_translate("MainWindow", "Male"))
        self.label.setText(_translate("MainWindow", "Select your gender:"))
        self.radioButton_female.setText(_translate("MainWindow", "Female"))

# Driver Code
if __name__ == "__main__":
    app = QtWidgets.QApplication(sys.argv)

    MainWindow = QtWidgets.QMainWindow()
    ui = Ui_MainWindow()
    ui.setupUi(MainWindow)
    MainWindow.show()
    sys.exit(app.exec_())

Output:

According to user’s choice a message will appear “You are male” or “You are female” and which will change as user changes his/her selection.
