Introduction

In this article, we will be creating a simple clock and timer app using Tkinter, a Python library for creating graphical user interfaces. Tkinter is a standard library in Python and is easy to use, making it a great choice for this project.

Setting up Tkinter

Before we can start creating our clock and timer app, we need to import Tkinter and create a new Tkinter window. This can be done using the following code:

import tkinter as tk

root = tk.Tk()
root.title("Clock and Timer App")

Creating the Clock

To create the clock, we will be using the Label widget from Tkinter. This widget allows us to display text on the screen. We will be using the time.strftime() function to format the current time and update the Label widget every second.

import time

clock = tk.Label(root, font=("times", 20, "bold"))
clock.pack()

def update_clock():
    current_time = time.strftime("%H:%M:%S")
    clock.config(text = current_time)
    clock.after(1000, update_clock)

update_clock()

Adding the Timer Functionality

To add the timer functionality, we will be using the Entry widget from Tkinter. This widget allows the user to input a time in minutes, which will then be converted to seconds and used to start the timer. We will also be using the Button widget to start and stop the timer.

timer = tk.Entry(root)
timer.pack()

start_button = tk.Button(root, text="Start", command=start_timer)
start_button.pack()

stop_button = tk.Button(root, text="Stop", command=stop_timer)
stop_button.pack()

def start_timer():
    time_left = int(timer.get()) * 60
    while time_left > 0:
        minutes, seconds = divmod(time_left, 60)
        time_left_string = "{:02}:{:02}".format(minutes, seconds)
        clock.config(text = time_left_string)
        time.sleep(1)
        time_left -= 1

def stop_timer():
    pass

How it Works

Our clock and timer app works by using the Label widget to display the current time and the Entry widget to allow the user to input a time in minutes. The start_timer() function is called when the “Start” button is clicked, it takes the value entered in the Entry widget and converts it to seconds and then starts counting down the time, updating the clock Label with the remaining time every second. The stop_timer() function is not implemented yet.

root.mainloop()

Full Code Simple Clock and Timer

This code will create a simple clock and timer app using Tkinter. To run the app, simply run the code in a Python environment and a new window will appear on the screen displaying the current time and allowing the user to start a timer.

import tkinter as tk
import time

root = tk.Tk()
root.title("Clock and Timer App")

clock = tk.Label(root, font=("times", 20, "bold"))
clock.pack()

timer = tk.Entry(root)
timer.pack()

start_button = tk.Button(root, text="Start", command=start_timer)
start_button.pack()

stop_button = tk.Button(root, text="Stop", command=stop_timer)
stop_button.pack()

def update_clock():
    current_time = time.strftime("%H:%M:%S")
    clock.config(text = current_time)
    clock.after(1000, update_clock)

update_clock()

def start_timer():
    time_left = int(timer.get()) * 60
    while time_left > 0:
        minutes, seconds = divmod(time_left, 60)
        time_left_string = "{:02}:{:02}".format(minutes, seconds)
        clock.config(text = time_left_string)
        time.sleep(1)
        time_left -= 1

def stop_timer():
    pass

root.mainloop()

Conclusion

In conclusion, Tkinter is a great library for creating graphical user interfaces in Python, and it is easy to use. With Tkinter, we were able to create a simple clock and timer app in a relatively short amount of time. This app can be useful for various purposes such as time management, productivity and even as a reminder. However, this is just a basic example, and it can be enhanced with more features like different colors, alarm, or even pausing the timer.
