Since this is a python file, it should follow the python rules where an empty string is treated as false:

```
$ python3
Python 3.10.6 (main, Aug 10 2022, 11:19:32) [GCC 11.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> x = ''
>>> 'foo' if x else 'bar'
'bar'
```
