Python to create a digital clock using Tkinter

Python Tkinter can be used to create all kinds of GUI programs for the web and desktop. In this article we will see how to create a digital clock displaying hour, minute and seconds live.

We use the time module to import the method strftime which displays the time in Hour, minute and seconds format. We create a canvas to hold these values. We refresh the values of strftime after every 200 milli seconds. We define a recursive function to achieve this.

Example

import time
from tkinter import *
canvas = Tk()
canvas.title("Digital Clock")
canvas.geometry("350x200")
canvas.resizable(1,1)
label = Label(canvas, font=("Courier", 30, 'bold'), bg="blue", fg="white", bd =30)
label.grid(row =0, column=1)
def digitalclock():
   text_input = time.strftime("%H:%M:%S")
   label.config(text=text_input)
   label.after(200, digitalclock)
digitalclock()
canvas.mainloop()

Output

Running the above code gives us the following result −
