python - How to use fixtures within setup_function and teardown_function in pytest

Question

I have a test where I need setup/teardown to be run for each test function:

class A:
    def setup(self):
        return 'setup'

    def teardown(self):
        return 'teardown'

@pytest.fixture(scope='function')
def a():
    return A()

def setup_function(a):
    logger.info(a.setup())

def test_a(a):
    logger.info('test_a')

def teardown_function(a):
    logger.info(a.teardown())

a contains the function test_a and not the fixture in setup_function and teardown_function. How can I access the fixture a within these functions?
