If a positive integer equal to itself in addition to all other divisors sum, it is called perfect number. 
For example: the number of totally 6, * because 6 = 1 + 2 + 3 ; 
a completely numbers are 28 = 14 + 7 + 4 + 2 + 1 . 
COMPLETE following number 1000

 

Problem-solving ideas

Outer loop number within 6-1000

All numbers divisible by number in the current cycle, and add to a list

That sums up whether to compare the current figures are the same

 

answer

all = []
for num in range(6, 1001):
    lists = []
    for n in range(1, num):
        if num % n == 0:
            lists.append(n)
    if sum(lists) == num:
        all.append(num)
print(all)
