Black seems to be in fashion. Adopting it would rid us of code style related worries.

If we decide to use it, we should consider using the following integrations:

• integrate Black with IDEs used by developers, when possible
• have a simple command to reformat all files with Black (or just check conformity)
• have a git pre-commit hook that performs Black reformatting (e.g. this tutorial which shows how to do it without using pre-commit.com, which would be an option too)
• have Black check the code under GitHub Actions CI

Black would replace autopep8 that we're currently using. There's still a need for flake8 checks, because flake8 checks other things than just pep8 code style.
