          return False
       perfect_sum = 0
       for i in range(1,n):
          if n%i==0:
             perfect_sum += i
       return perfect_sum == n

    max_value = int(input())
    # calling function and print perfect numbers
    print('Perfect numbers from %d to %d are:' %(min_value, max_value))
    for i in range(min_value, max_value+1):
       if perfect_Number(i):
