Countdown Timer Basics
Introduction
Let’s try doing something else. Let’s make a simple timer app that will get a set number of seconds and count down from that!
Components Needed
- Little Python Brain
- A tablet/phone/laptop
Steps
1
Importing the sleep library
We need this block to count down each second.
2
Setting the time
We then take the user input of how many seconds they want to count down from.
3
Converting the string to integer
Recall that taking a User_Input returns a string data type. We need to convert this data to integer first. Call this variable setTime.
4
Our countdown loop
We then use another for loop, this time counting down every second from setTime down to 0.
Every second, it also prints out the seconds remaining.
5
Time's up!
Finally, once the loop is finished, we want to tell the user that. A simple print() block will do the trick!
