Answer 2

Answer:

   try:

       num = input("Enter a number: ")

       if num == 'done':

       n = int(num)

       if largest is None or n > largest:

           largest = n

elif smallest is None or n < smallest:

           smallest = n

   

   except:

       print("Invalid input")

       continue

print("Maximum is", largest)
