Use multiple parameters yielded by a request fixture in pytest

Question

how can I yield multiple parameters in a request fixture and use these as arguments in a test function? Below is a sample code of the request fixture

@pytest.fixture(params=range(ITERNUM))
def data(request):
    yield request.param

def test_01(data):
    print(data)

I would like to have custom Ids for each data e.g. current output of the test name is data[01]. I would like to output more customized test ID e.g. 'test-name[value_of_data]'

It would be similar approach as that explained here but the test id string should be created dynamically for each value of data.

Is it possible?

Thanks, Archie

Resolved it by passing a callable to the ids parameter of the fixture.
