Напишите программу, которая проверит, что число является совершенным. Совершенное число - натуральное число, равное сумме всех своих собственных делителей. Например, число 6 равно сумме своих собственных делителей 1 + 2 + 3.
Примеры совершенных чисел:
6, 28, 496, 8128
Решение:
def get_divisors(num): divisors = [] for i in range(1, num): if num % i == 0: divisors.append(i) return divisors
def perfect_num(num): divisors = get_divisors(num) return num == sum(divisors)
