You can fix coding style using Black with:

nox -s black_fix

You can run test on all supported Python versions or on a specific Python version with:

nox -s test       # Run on all Python version

nox -s test-3.8   # Run on Python 3.8
nox -s test-3.9   # Run on Python 3.9
nox -s test-3.10  # Run on Python 3.10
nox -s test-3.11  # Run on Python 3.11
nox -s test-3.12  # Run on Python 3.12

And you can build the documentation with (result in build/html/):
