python怎么找出一千以内的完数

完数是指一个正整数的所有因子（包括1，不包括自身）的和等于这个数本身。下面是一个Python程序，用来找出一千以内的完数：

def find_perfect_numbers(limit):
    perfect_numbers = []
    for num in range(1, limit):
        factors = []
        for i in range(1, num):
            if num % i == 0:
                factors.append(i)
        if sum(factors) == num:
            perfect_numbers.append(num)
    return perfect_numbers

limit = 1000
perfect_numbers = find_perfect_numbers(limit)

print("Perfect numbers within 1000:")
for num in perfect_numbers:
    print(num)

运行这个程序，就可以找到一千以内的完数。
