Python linting (black) is failing

To keep the code consistent with lots of contributors, we run automated code consistency checks.
To fix this CI test, please run:

• Install black: pip install black
• Fix formatting errors in your pipeline: black .

Once you push these changes the test should pass, and you can hide this comment 👍

We highly recommend setting up Black in your code editor so that this formatting is done automatically on save. Ask about it on Slack for help!

Thanks again for your contribution!

btw. why is this pipeline not using the pre-commit.config.yaml from the template?

It might be because we have not updated the template in a long time. I tried to do it a few weeks ago, but the number of changes made it difficult and I felt I needed to start over. I am trying again now.
