i need help on a python code project for a countdown output.
I was asked to use a while loop to make a countdown this is the code I wrote number = int(input()) #use a while loop for the countdown while number > 0: print(number) number = number - 1 and the expected output was supposed to be (e.g. if the user input is 5 the output should look this) 5 4 3 2 1 0 but my output doesn't end with 0 and i don't why. please i need help

Your code first prints the number, then decreases by 1. So when number becomes 1, is printed, then becomes 0.
But then the loop stops because 0 > 0 is false. So you need to make sure that it will still be true for number = 0.

The reason your output is not ending with 0 is because your while loop stops when number is equal to 0, but it doesn't print 0 because the loop stops before it reaches that point. To include 0 in the output, you can modify your loop condition. Here's the corrected code:number = int(input())
# use a while loop for the countdown
while number >= 0: # Changed condition to include 0
print(number)
number = number - 1
Now, when you input 5, for example, the output will be:5
4
3
2
1
0
Now the loop will run until number becomes 0, and it will print 0 as well before ending.

You have to modify the while loop by changing the condition as:
while number >= 0

thanks guys i really appreciate.

The condition while loop must be
while number >= 0
because the loop will stop when number > 0
