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: 

Python3

# 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()
