Obtain with pip install battery-yunruse and use like;
import battery
source = 'battery' if battery.is_discharging() else 'AC power'
print(f'On {source} at {battery.percent()}%')
print(f'Battery is at {battery.capacity() / battery.design_capacity()*100:4.1f}% health.')The CLI always returns a JSON value:
$ python -m battery
{"is_discharging": true, "percent": 92, "minutes_to_empty": 215, "minutes_to_full": null, "capacity": 2388, "design_capacity": 4381}
$ python -m battery percent
92

Note that the Python is just a wrapper around the annotated .toml of commands that give standardised output.
