StopWatch using Python

Hope you are doing great!

Today, We are going to see how can we create a StopWatch using Python

For this, we need the tkinter module and Datetime module.

Tkinter is the standard GUI library for Python. Python when combined with Tkinter provides a fast and easy way to create GUI applications.

Datetime module supplies classes to work with date and time. These classes provide a number of functions to deal with dates, times, and time intervals.

To install tkinter module python, type the below command in your terminal–

pip install tkinter 

To install datetime module python, type the below command in your terminal–

pip install datetime

So, here is our StopWatch. Simple isn’t it?? This is how we have successfully done with the ‘StopWatch using Python’. I hope the ‘Tkinter and DateTime library is now more clear to you and don’t forget to try this code once!!

You can play around with the library, explore more features and even customize it further.

ThankYou Pythoner’s!!!
