Python | Create a digital clock using Tkinter

As we know Tkinter is used to create a variety of GUI (Graphical User Interface) applications. In this article we will learn how to create a Digital clock using Tkinter.

Prerequisites:
-> Python functions
-> Tkinter basics (Label Widget)
-> Time module

Using Label widget from Tkinter and time module :
In the following application, we are going to use Label widget and also going to use time module which we will use to retrieve system’s time.

Below is the implementation:

# importing whole module 
from tkinter import * 
from tkinter.ttk import *
  
# importing strftime function to 
# retrieve system's time 
from time import strftime 
  
# creating tkinter window 
root = Tk() 
root.title('Clock') 
  
# This function is used to  
# display time on the label 
def time(): 
    string = strftime('%H:%M:%S %p') 
    lbl.config(text = string) 
    lbl.after(1000, time) 
  
# Styling the label widget so that clock 
# will look more attractive 
lbl = Label(root, font = ('calibri', 40, 'bold'), 
            background = 'purple', 
            foreground = 'white') 
  
# Placing clock at the centre 
# of the tkinter window 
lbl.pack(anchor = 'center') 
time() 
  
mainloop()
