- Removed the `else:` statement from the `while` loop as `break` exits the loop instantly
- Updated the final print statement to use the unpacked data from the `Room` instance
- Minor formatting updates
Check out [PEP 8](http://legacy.python.org/dev/peps/pep-0008/) for rules on Python formatting (this is the next course I'm releasing). But, summary:

```python
class Foo:
    def bar(self):
        return 1

    def bar(self):
        return 2


def foo():
    return 2
```

Two lines between 1st level classes/functions, one line between class methods, no lines after a function/method definition. Extra lines inside code as needed for readability.
