In this article we will see how to create a digital clock using PyQt5, this digital clock will basically tells the current time in the 24 hour format.

In order to create a digital clock we have to do the following:

1. Create a vertical layout
2. Create label to show the current time and put it in the layout and align it to the center.
3. Create a QTimer object
4. Add action to the QTimer object such that after every 1sec action method get called.
5. Inside the action method get the current time and show that time with the help of label.

Below is the implementation –

# importing required librarie
import sys
from PyQt5.QtWidgets import QApplication, QWidget
from PyQt5.QtWidgets import QVBoxLayout, QLabel
from PyQt5.QtGui import QFont
from PyQt5.QtCore import QTimer, QTime, Qt
class Window(QWidget):
    def __init__(self):
        # setting geometry of main window
        self.setGeometry(100, 100, 800, 400)
        # creating a vertical layout
        layout = QVBoxLayout()
        # creating font object
        font = QFont('Arial', 120, QFont.Bold)
        # creating a label object
        self.label = QLabel()
        # setting centre alignment to the label
        # setting font to the label
        # adding label to the layout
        # setting the layout to main window
        # creating a timer object
        timer = QTimer(self)
        # adding action to timer
        # update the timer every second
    # method called by timer
    def showTime(self):
        # getting current time
        current_time = QTime.currentTime()
        # converting QTime object to string
        label_time = current_time.toString('hh:mm:ss')
        # showing it to the label
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# showing all the widgets
# start the app
