I am getting the required result for the following code. But still I have been given wrong. what went wrong?

def countdown(n):
    i = 1
    while i <= n:
        print n
        n = n - 1
    return 'Blastoff!'

print countdown(4)

My quick answer was "You must print "Blastoff!", not return it. This has been covered in other question threads. Please check for that before starting a new thread."

However, I see that your question is deeper. You did print "Blastoff!" What is wrong with your answer is that the automatic grader will execute your countdown function only, rather than the whole of your code. Your interpretation of the problem statement is reasonable, but understanding the grading process will help you resolve such ambiguities.

Ok accepted! I will be more careful in near future. Hope it goes well and average score remains above 70%. thanks for your prompt replay and explanation.

We were asked to write a procedure that prints the numbers from n to 1 followed by the word "Blastoff!".

You have written a procedure that prints the numbers and returns the word "Blastoff!".

If it's called as the object of a print command, the output will look similar on the screen. But it's really not the same thing at all.

You returned "Blastoff!" instead of printing it.

The countdown function should print everything without the use of a print statement to call it.

ex:

countdown(3)

3
2
1
Blastoff!
