# 1. countdown & countup application # ✓ The code of your program. # ✓ Output for the following input: a positive number, a negative number, and zero. # ✓ An explanation of your choice for what to call for input of zero.

# Count down from a positive number def countdown(n): if n == 0: print(Fore.YELLOW + 'Blastoff!') else: print(n) countdown(n - 1)
