Answer:
The answer is "Option b".
Explanation:
Sentinel [..] is a special value, which existence ensures the end of a loop, which performs structured data. It allows the information end to be identified where no other means are available for this, and wrong choices can be described as follows:
- In option a, It is a special value, not a data type, that's why it is not correct.
- Option c and Option d both were wrong because, It is an empty list, and it can't indicate the starting point of the list and guards the list.
Answer:
def countdown(n):
if n <= 0:

print(n)
countdown(n-1)
def countup(n):
if n >= 0:
print('Blastoff!')
else:
print(n)
countup(n+1)
number = int(input("Enter a number: "))
if number >= 0:
countdown(number)
elif number < 0:
countup(number)
<u>Outputs:</u>
Enter a number: 3
3
2
1
Blastoff!

For the input of zero, the countdown function is called.
Explanation:
Copy the countdown function
Create a function called countup that takes one parameter, n. The function counts up from n to 0. It will print the numbers from n to -1 and when it reaches 0, it will print "Blastoff!".
Ask the user to enter a number
Check if the number is greater than or equal to 0. If it is, call the countdown function. Otherwise, call the countup function.
