I'd use the

```python
    'special '
    'string concatenation '
    'notation'
```
that python offers instead of this. It's more idiomatic and also results in your string not being formatted like this:

This string is equivalent to 'Check "Opt out of emails about new features                                 and other CommCare updates." below and then                                 click "Update Information" if you do                                not want to receive future emails from us.'

(which may not matter but is certainly not what you intended)
