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!

Sorry, it looks like I added an extra colon on most of the lines... I did the editing on the web interface 🫢

Maybe revert or just add another commit to fix it?

Fixed in my PR.
