-### Ordering of imports
-
-Instead of ordering the imports manually, use [`isort`](https://github.com/PyCQA/isort).

-```shell
-pip3 install isort
-isort homeassistant/components/sensor/fixer.py
-```

 Prefer [f-strings](https://docs.python.org/3/reference/lexical_analysis.html#f-strings) over `%` or `str.format`.
