@[qianyan_](/user/339332) 为啥`print(ans)`

@[qianyan_](/user/339332)
原来的代码如果$s \ge L$就会多输出一个
```python
L=int(input())
s=0
ans=[]
if L<=1:
print(0)
else:
for i in range(2,100000):
if s>=L:
break
else:
for j in range(2,i):
if i%j==0:
break
else:
if s+i<=L:
ans.append(i)
s+=i
else:
break
for num in ans:
print(num)
print(len(ans))
```
就好了

$s> L$

写错了
by ADay @ 2020-04-22 21:29:19
```python
L=int(input())
s=0
ans=[]
if L<=1:
print(0)
else:
while True:
for i in range(2,100000):
if s>=L:
break
else:
for j in range(2,i):
if (i%j==0):
break
else:
ans.append(i)
s+=i
break
for num in ans:
print(num)
print(len(ans))
```
@[ADay](/user/312393) 不好意思哈，debug的时候加的，忘删了，是这个

改成这样：
```python
L=int(input())
s=0
ans=[]
if L<=1:
print(0)
else:
for i in range(2,100000):
if s>=L:
break
else:
for j in range(2,i):
if i%j==0:
break
else:
if s+i<=L:
ans.append(i)
s+=i
else:
break
for num in ans:
print(num)
print(len(ans))
```

@[ADay](/user/312393) 可是改成大于样例就过不去，就是原代码试了好多个都是可以，边界也特判了，找不出来bug

@[qianyan_](/user/339332) 不是改成大于，是在每次`s+=i`时判断

@[ADay](/user/312393) 哇哦，懂了，谢谢谢谢！
