Count down using while loop in python

sure! here's a tutorial on how to create a countdown using a while loop in python:

a countdown is a sequence of numbers that are typically displayed in reverse order, starting from a specified number and ending at 0.

in python, you can create a countdown using a while loop by initializing a variable with the starting number and then decrementing it in each iteration of the loop until it reaches 0.

here's an example code snippet that demonstrates a simple countdown from 5 to 0 using a while loop:

in this example:
1. we initialize the variable `count` with the value 5 as the starting number for the countdown.
2. the while loop continues as long as the value of `count` is greater than or equal to 0.
3. inside the loop, we print the current value of `count` and then decrement it by 1 in each iteration using the `count -= 1` statement.
4. the loop will continue until `count` reaches 0, at which point the loop will exit, and "blast off!" will be printed to indicate the end of the countdown.

you can customize the starting number and the ending message to create countdowns with different ranges and messages. feel free to experiment with the code and add your own creative touches!
