In this video, we’ll build a versatile countdown timer in Python that lets you enter the time in seconds or minutes:seconds format. You’ll see the program handle user input, validate it, and run a smooth live countdown right in the console.

Here’s what you’ll learn in this tutorial:

◼️ How to use input() to get data from the user
◼️ How to validate user input with try/except
◼️ How to use a while loop to allow repeated attempts for valid input
◼️ How to format time in minutes and seconds
◼️ How to create a real-time countdown using time.sleep()
◼️ How to print output cleanly on the same line

We’ll go step by step, showing you the live output, so by the end, you’ll have a fully working interactive timer that you can tweak or expand for your own Python projects.

💡 Stay tuned for more Python examples and tutorials — keep learning and coding!
