How can I use return of fixture function and data which will be used as parameterized in pytest test case

Question

I get some parameters from command lines. Then I want to use these parameters as variables in test cases. I want to use parametrised test in same test case. Is it correct to run it as below?

conftest.py

import pytest

def pytest_adoption(parser):
    parser("--arg1",action="store",help="first argument")
    parser("--arg2),action="store",help="second argument")

example_test.py

import pytest

test_data = [("name1","surname1",40),("name2","surname2",30)]

@pytest.fixture(autouse=True)
def getArg(pytestconfig):
    arg1 = pytestconfig.getoption("arg1")
    arg2 = pytestconfig.getoption("arg2")
    return arg1,arg2

@pytest.mark.parametrize("name,surname,age",test_data)
def test_example(name,surname,age):
    assert type(getArg) == tuple
    arg1,arg2 = getArg
    if arg1 == "first" && arg2 == "second" :
       print('My name is {} {} and I am {} years old'.format(name,surname,age)) 

execution:

pytest example_test.py --arg1 "first" --arg2 "second"

I found answer as fixture function will be given as a test argument:

@pytest.mark.parametrize("name,surname,age",test_data)
def test_example(getArg,name,surname,age):
    assert type(getArg) == tuple
    arg1,arg2 = getArg
    if arg1 == "first" && arg2 == "second" :
       print('My name is {} {} and I am {} years old'.format(name,surname,age))
