Merged `else` and its single `if`, changed style to be more consistent

Following Mark's reviews:
- The single `if` inside the `else` can be merged with its `else` - this will reduce the level of complexity and indentation.
- Changed from style
```py
new = ('hello'
       'world')
```
    to
```py
new = (
    'hello'
    'world'
)
```
    to be more consistent with the rest of the code
