How to ask Pytest to run a specific test in a python script?

If I have multiple tests running in a script, e.g.:

import pytest

@pytest.mark.parametrize("test_input,expected", [
    ("3+5", 8),
    ("2+4", 6),
    ("6*9", 42),
])
def test_eval(test_input, expected):
    assert eval(test_input) == expected

@pytest.mark.parametrize('test_input,expected', [
        (1,1),
        (2,2),
        (2,3),
        ])
def test_equal(test_input,expected):
    assert test_input == expected


if __name__ == '__main__':
    '''
    Test Zone!
    '''
    #executing the tests
    pytest.main([__file__])

How can I use the last line pytest.main([__file__]) to run one of the tests at a time instead of running all of them at once?

Using pytest.main() acts like calling pytest from the command line according to the pytest documentation. You can pass in commands and arguments to this, allowing you to use the -k flag to specify tests via a keyword expression:

pytest.main(["-k", "test_func"])

You can also you specify tests via node id:

pytest.main(["test_mod.py::test_func"])
