编写程序，直接在函数中输出小于等于j的完备数及其所有约数

好的，以下是一个简单的 Python 代码，可以输出小于等于 j 的完备数及其所有约数：

def perfect_numbers(j):
    for num in range(1, j+1):
        sum_divisors = sum(i for i in range(1, num) if num % i == 0)
        if sum_divisors == num:
            print(num, "is a perfect number and its divisors are:", end=" ")
            for i in range(1, num):
                if num % i == 0:
                    print(i, end=" ")
            print()

# 测试
perfect_numbers(10000)

运行结果：

6 is a perfect number and its divisors are: 1 2 3 
28 is a perfect number and its divisors are: 1 2 4 7 14 
496 is a perfect number and its divisors are: 1 2 4 8 16 31 62 124 248 
8128 is a perfect number and its divisors are: 1 2 4 8 16 32 64 127 254 508 1016 2032 4064 

希望这个代码能够回答您的问题！
