源代码：

ll = float(input())
sum = 1
zs = [2, ]
gt = 2
x = 3
while (gt < ll):
    flag = 1
    for i in range(2, x, 1):
        if (x % i == 0):
            flag = 0
            break
    if (flag == 1):
        if (gt + x <= ll):
            zs.append(x)
            sum += 1
            gt += x
        else:
            break
    x += 2
for j in zs:
    print(j, end="\n")
print(sum)

为啥错了？？编译器中可以编译，但洛谷就报错了 下面是编译信息
