Is this the best way to return list like thing?

pytest_iter_mock.py

@pytest.fixture
def mock_time_in_ms(monkeypatch):
    def _mock_time_in_ms(values_to_return):
        idx = [0]

        def _time():
            v = values_to_return[idx[0]]
            idx[0] += 1
            return v

        monkeypatch.setattr(some_module_that_uses_time_in_ms, 'time_in_ms', _time)

    return _mock_time_in_ms
