Exclude multiple marked tests with pytest from command line

Question

I have the following in my pyproject.toml

[tool.pytest.ini_options]

markers = [
    "plot: marks SLOW plot tests (deselect with '-m \"not plot\"')",
    "open_tutorial: marks the open_tutorial (which opens VSCode all the times)"
]

and I have a bunch of test methods marked accordingly.

If I run

coverage run --branch -m pytest -m "not open_tutorial"

or

coverage run --branch -m pytest -m "not plot"

I got the desired results, namely the marked test are skipped, but I cannot figure out how to make pytest to skip both. I tried the following

coverage run --branch -m pytest -m "not open_tutorial" -m "not plot"
coverage run --branch -m pytest -m "not open_tutorial" "not plot"
coverage run --branch -m pytest -m ["not open_tutorial","not plot"]

but none of them worked.

According to pytest help:

-m MARKEXPR only run tests matching given mark expression. For example: -m 'mark1 and not mark2'.

If you want to use more than one marker you should use the and operator.

pytest -m "not open_tutorial and not plot"

will run all test without marks: open_tutorial and plot

but:

pytest -m "not open_tutorial and not plot and othermark"

will run tests with othermark if they don't have plot or open_tutorial marks.
