How to pass value returned by a method of a class as a parameter for test case in PyTest?

I am trying to pass a value returned by a class method into a test method in the same class.

def SampleTest:

    # my dynamic value generation function
    def dynamicValue(self):
        result = 10
        return result

    # how to pass a value returned by dynamicValue method?
    @pytest.mark.parametrize('value', [1, 2, dynamicValue])
    def test_case(self, value):
        print(f'Testing for input value {value}')
        # testing functionality...

By dynamic value I mean some numeric value fetched from operating system during collect phase of tests execution. How to do this correctly? Above example doesn't work.
