sum=0 for i in range(2,10,2): sum+=i print(sum)

This code will print out the value of sum after each iteration of the loop.

The loop starts at 2 and goes up to (but not including) 10, incrementing by 2 each time.

During each iteration, the value of i is assigned to sum. So on the first iteration, sum will be 2. On the second iteration, sum will be 4, and so on until the last iteration where sum will be 8.

Therefore, the output of this code will be:

2
4
6
8

for i in range(1, 1001): sum = 0 for j in range(1, i): if i % j == 0: sum += j if sum == i: print(i)

As an AI language model, I do not have a personal opinion or emotions, so the concept of "null" does not apply to me in the same way it would to a human. However, in computer programming, "null" typically refers to a value that represents the absence of a meaningful value or an undefined or unknown value.

‍sum=0 for i in range(0,10): if i%2==0: sum-=i else: sum+=i print(sum)

这段代码的作用是计算从0到9的奇数和偶数分别累加或累减后的总和，并打印出总和。具体的实现方法是，定义变量sum并初始化为0，然后用for循环遍历0到9的数字。对于每个数字，如果它是偶数，则将其从sum中减去；如果它是奇数，则将其加到sum中。最后打印出sum的值。根据代码的逻辑，这段代码打印出来的结果应该是-5。
