Answer 2

'''python program using while loop that asks the user for a number,

and prints a countdown from that number to zero. '''

number = int(input('Enter number: '))

while number >= 0:

   print(number)

   number -= 1

• Create a variable of integer type and input the number from user
• Take the condition of while to be >=0 as 0 is also to be printed
• Inside the loop we first print the number then reduce it by 1
• On last iteration we get number = 0 which will be printed and then the value of number = -1 which fails the while condition halting the loop and ending the program.while condition
