Introduction
Python stopwatch is a tkinter based project. Python stopwatch project uses tkinter python library that provides graphical user interface. It is easy to use and implement.
Creating a timer in Python using Tkinter is a great starter project for learning GUI programming and event handling. Tkinter is Python’s built-in toolkit for constructing graphical interfaces, making it simple to develop applications without the need for additional installs. The stopwatch features a digital time display and three buttons: Start, Stop, and Reset. When you press the Start button, the timer starts counting time in milliseconds with the after() method, which updates the time every 100 milliseconds. The Stop button pauses the timer, while the Reset button resets it to zero.

Key components include Tkinter widgets.
- Button widgets manage user interactions, whereas labels display time.
- Time Module: This aids in determining elapsed times.
- The after() method schedules a function to run after a specified time period, allowing the stopwatch to update dynamically.
Implementation Steps
- Initialize Tkinter: Create a Tkinter window and configure its title and size.
- Create UI elements: Add labels and buttons to facilitate user interaction.
- Handle Timer Functions. Implement functions for starting, stopping, and resetting the timer.
- Update the display: To keep the timer updated, use the after() function.
