### Sadece modern Python

Read more about it in the [FastAPI docs about Response Status Code](https://fastapi.tiangolo.com/tutorial/response-status-code/).

## Example

```python
from fastapi import FastAPI, status

app = FastAPI()


@app.get("/items/", status_code=status.HTTP_418_IM_A_TEAPOT)
def read_items():

client = TestClient(app)


def test_get():
    response = client.get("/typer", follow_redirects=False)
    assert response.status_code == 307, response.text
    assert response.headers["location"] == "https://typer.tiangolo.com"


def test_openapi_schema():
    response = client.get("/openapi.json")
    assert response.status_code == 200, response.text
    assert response.json() == {
        "openapi": "3.1.0",

There are several custom response classes you can use to create an instance and return them directly from your *path operations*.

Read more about it in the [FastAPI docs for Custom Response - HTML, Stream, File, others](https://fastapi.tiangolo.com/advanced/custom-response/).

You can import them directly from `fastapi.responses`:
