1. We still import `field` from standard `dataclasses`.

2. `pydantic.dataclasses` is a drop-in replacement for `dataclasses`.

3. The `Author` dataclass includes a list of `Item` dataclasses.

4. The `Author` dataclass is used as the `response_model` parameter.

5. You can use other standard type annotations with dataclasses as the request body.

    In this case, it's a list of `Item` dataclasses.

It is also built to work as a future reference so you can come back and see exactly what you need.

## Run the code

All the code blocks can be copied and used directly (they are actually tested Python files).

To run any of the examples, copy the code to a file `main.py`, and start `fastapi dev` with:

<div class="termy">

```console

    }

    @Test
    void testCollectDependencies() throws Exception {
        Artifact artifact = new DefaultArtifact("ut.simple:artifact:extension:classifier:1.0");
        // notice: extension and classifier not really used in this test...

        CollectRequest collectRequest = new CollectRequest();
        collectRequest.setRoot(new Dependency(artifact, null));
        collectRequest.addRepository(newTestRepository());

func TestGetObjectInfo(t *testing.T) {
	ExecObjectLayerTest(t, testGetObjectInfo)
}

// Testing GetObjectInfo().
func testGetObjectInfo(obj ObjectLayer, instanceType string, t TestErrHandler) {
	// This bucket is used for testing getObjectInfo operations.
	err := obj.MakeBucket(context.Background(), "test-getobjectinfo", MakeBucketOptions{})
	if err != nil {
		t.Fatalf("%s : %s", instanceType, err.Error())
	}
	opts := ObjectOptions{}

In previous versions of Python, you could have used threads or <a href="https://www.gevent.org/" class="external-link" target="_blank">Gevent</a>. But the code is way more complex to understand, debug, and think about.

In previous versions of NodeJS / Browser JavaScript, you would have used "callbacks". Which leads to <a href="http://callbackhell.com/" class="external-link" target="_blank">callback hell</a>.
