编辑器写好运行可以，直接终端输入就报错

#4 Created at ... [Delete] [Delete and Lock User] 
for x in [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]:
...     sum = sum + x <==================== 在这里按两次回车
...

print(sum) <==================== 再输入print

操作了一下，两个回车无错，谢谢啊！

#6 Created at ... [Delete] [Delete and Lock User]

老师，我看你教程里面没有在sum=sum+x后面加上两个回车键。我这里为什么要两次回车呢？方便讲解一下吗？

廖雪峰

#7 Created at ... [Delete] [Delete and Lock User]

看到...表示代码块要缩进。现在你想取消缩进，只能再敲一个回车

for x in [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]:
...     sum = sum + x <==================== 在这里按回车
... <==================== 再按回车
<==================== for循环的缩进已取消
