very bad instructions

No, your interpretation is not correct, but at least it's possible to read. It should be:

```python
...your code here...
```

About your problem: your answer is no correct, it has an unnecessary trailing newline. There should be no \n at the end.

You have not read the point mentionig the code formatting, have you.

With description so vague there's no way to properly address it. I will close it as invalid, and you can post again with some better explanation. But before you post again, please read this paragraph and this paragraph.

Read the last bullet point of this paragraph.

At the location where you should put the result, you've put None.
Where should the result go?
