◼️ 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.
