In this tutorial, I am going to show you an example how to use the QCheckBox widget with PyQt5 in Python.
A checkbox is a small interactive box which you can click inside the box and toggle between the value between True and False.
Checkboxes are quite useful when you want to give a user a set of questions with Yes or No, True or False response.

Python Source Code:
import sys
from PyQt5.QtWidgets import QApplication, QWidget, QVBoxLayout, QCheckBox
from PyQt5.QtCore import Qt
class AppDemo(QWidget):
def __init__(self):
super().__init__()
self.vLayout = QVBoxLayout()
self.checkbox_A = QCheckBox('A')
self.checkbox_B = QCheckBox('B')
self.checkbox_A.stateChanged.connect(self.selectChkboxA)
self.checkbox_B.stateChanged.connect(self.selectChkboxB)
self.vLayout.addWidget(self.checkbox_A)
self.vLayout.addWidget(self.checkbox_B)
self.setLayout(self.vLayout)
def selectChkboxA(self, checked):
if Qt.Checked == checked:
print('Checkbox A is checked')
else:
print('Checkbox A is unchecked')
def selectChkboxB(self, checked):
if Qt.Checked == checked:
print('Checkbox B is checked')
else:
print('Checkbox B is unchecked')
if __name__ == '__main__':
app = QApplication(sys.argv)
demo = AppDemo()
demo.show()
app.exit(app.exec_())
