Formatting with black and isort

isort and black are added as development dependencies. black and isort can be used to format the code with

make format

And the code style can be checked with

make check

Settings for both black and isort can be edited in pyproject.toml. The default settings are:

[tool.black]
line-length = 120
include = '\.pyi?$'
target-version = ['py39']
fast = true
exclude = '''
(
  /(                        # exclude a few common directories in the
    \.git                   # root of the project
    | \.pytest_cache
    | python-venv
    | \.venv
    | build
    | dist
    | \.tox
  ))
'''

[tool.isort]
profile = "black"

If include_github_actions is set to "y", code formatting is checked for every merge request, every merge to main, and every release.
