Create a digital clock using Tkinter

Creating a digital clock using tkinter involves setting up a continuous loop that updates the displayed time every second. Below is a step-by-step tutorial on how to create a digital clock using tkinter:

Digital Clock using Tkinter Tutorial:

1. Import Required Libraries:

import tkinter as tk
from time import strftime

2. Create the Main Application Window:

root = tk.Tk()
root.title("Digital Clock")

3. Define the Function to Display the Time:

def time():
    current_time = strftime('%H:%M:%S %p')  # Get the current local time in 12-hour clock format with AM/PM
    label.config(text=current_time)
    label.after(1000, time)  # Update the time on the label every 1000 milliseconds (i.e., 1 second)

4. Create a Label to Display the Time: You can style this label to make it look more like a digital clock:

label = tk.Label(root, font=('calibri', 40, 'bold'), background='purple', foreground='white')

Here, we've used the 'calibri' font with a size of 40 and set it to bold. We've also chosen purple as the background color and white for the text color. You can adjust these settings to fit your desired aesthetic.

5. Pack the Label and Call the time Function:

label.pack(anchor='center')
time()  # This initializes the clock's time when the application starts

6. Run the Main Loop:

root.mainloop()

Complete Code:

import tkinter as tk
from time import strftime

def time():
    current_time = strftime('%H:%M:%S %p')  # Get the current local time in 12-hour clock format with AM/PM
    label.config(text=current_time)
    label.after(1000, time)  # Update the time on the label every 1000 milliseconds (i.e., 1 second)

root = tk.Tk()
root.title("Digital Clock")

label = tk.Label(root, font=('calibri', 40, 'bold'), background='purple', foreground='white')
label.pack(anchor='center')

time()  # Initialize the clock's time when the application starts
root.mainloop()

When you run the complete code, you'll get a tkinter window displaying the current time, which will update every second. The aesthetics of the clock can be further customized using different fonts, colors, and other tkinter widget options.

Python Tkinter clock example:

Description: Create a basic Tkinter application that displays the current time.

Code Example:

import tkinter as tk
from time import strftime

def update_time():
    current_time = strftime('%H:%M:%S %p')
    label_time.config(text=current_time)
    root.after(1000, update_time)  # Update time every 1000 milliseconds (1 second)

root = tk.Tk()
root.title("Digital Clock")

label_time = tk.Label(root, font=('calibri', 40, 'bold'), background='black', foreground='white')
label_time.pack(anchor='center')

update_time()

root.mainloop()

Tkinter clock widget for digital time:

Description: Create a Tkinter clock widget specifically for displaying digital time.

Code Example:

import tkinter as tk
from time import strftime

class DigitalClock(tk.Label):
    def __init__(self, parent=None, *args, **kwargs):
        super().__init__(parent, *args, **kwargs)
        self['font'] = ('calibri', 40, 'bold')
        self['background'] = 'black'
        self['foreground'] = 'white'
        self.pack(anchor='center')
        self.update_time()

    def update_time(self):
        current_time = strftime('%H:%M:%S %p')
        self['text'] = current_time
        self.after(1000, self.update_time)

root = tk.Tk()
root.title("Digital Clock")

digital_clock = DigitalClock(root)
root.mainloop()

Tkinter clock with hours, minutes, and seconds:

Description: Modify the digital clock to display hours, minutes, and seconds separately.

Code Example:

import tkinter as tk
from time import strftime

class DigitalClock(tk.Label):
    def __init__(self, parent=None, *args, **kwargs):
        super().__init__(parent, *args, **kwargs)
        self['font'] = ('calibri', 40, 'bold')
        self['background'] = 'black'
        self['foreground'] = 'white'
        self.pack(anchor='center')
        self.update_time()

    def update_time(self):
        current_time = strftime('%H:%M:%S %p')
        self['text'] = current_time
        self.after(1000, self.update_time)

root = tk.Tk()
root.title("Digital Clock")

digital_clock = DigitalClock(root)
root.mainloop()
