你这段代码的作用是计算1到100的累加和,并将结果打印出来。可以将代码稍微修改一下,让它更加简洁:
```python
sum = 0
for i in range(1, 101):
sum += i
print("1-100的累加和为:", sum)
```
这段代码中,我们使用了Python中的`range()`函数来生成1到100的整数序列,然后使用`for`循环遍历这个序列,并将每个数累加到变量`sum`中。最后,使用`print()`函数将计算结果输出到屏幕上。

sum = 0for i in range(1, 101): sum += iprint(sum)
This Python code will print the sum of integers from 1 to 100, inclusive.
The code first initializes the variable "sum" to 0. It then uses a for loop to iterate through the range of numbers from 1 to 100 (not including 101). During each iteration of the loop, the variable "i" takes on the current value of the loop index.
Inside the loop, the code adds the value of "i" to the current value of "sum". This accumulates the sum of all the numbers from 1 to 100.
After the loop has finished, the code prints out the final value of "sum".
sum = 0 for i in range(1, 11): sum += i print(sum)
This code will output the value of the variable "sum" after each iteration of the for loop.
The output will be:
1
2
3
4
5
6
7
8
9
10
This is because the variable "sum" is being assigned the value of "i" in each iteration of the loop, and then the current value of "sum" is printed. Since "i" is incrementing from 1 to 10, the output will be the numbers 1 through 10 printed on separate lines.
Note that the initial value of "sum" is 0, but it is immediately overwritten in the first iteration of the loop. If the intention was to add up the values of "i" from 1 to 10, the code should be modified as follows:
sum = 0
for i in range(1, 11):
sum += i
print(sum)
This would output the value of the variable "sum" after the loop has completed, which would be the sum of the numbers from 1 to 10 (i.e. 55).
