Answer 1

Answer:

not sure if all right but what i know is this

Explanation:

def is_perfect_number(n):

  sum = 1

  i = 2

  while i * i <= n:

      if n % i == 0:

          sum = sum + i + n/i

          i += 1

          return (True if sum == n and n!=1 else False)

      num = int(input(“Enter a number : “))

      if(is_perfect_number(num)):

          print(num,”is a perfect number”)

          else:

              print(num,”is not a perfect number”)
