Dalam kondisi ini, ini berarti attribut JSON dan tipe data yang dimiliki, dll.

#### Schema OpenAPI and JSON

"schema" OpenAPI mendefinisikan skema API dari API yang anda buat. Skema tersebut termasuk definisi (atau "schema") dari data yang dikirim atau diterima oleh API dari **JSON Schema**, skema data standar JSON.

#### Lihat `openapi.json`

# Parameter Path

"parameter" atau "variabel" path didefinisikan dengan sintaksis Python format string:

{* ../../docs_src/path_params/tutorial001.py hl[6:7] *}

Nilai parameter path `item_id` akan dikirim ke fungsi sebagai argument `item_id`:

Jika anda menjalankan contoh berikut dan kunjungi <a href="http://127.0.0.1:8000/items/foo" class="external-link" target="_blank">http://127.0.0.1:8000/items/foo</a>, anda akan melihat respon:

```JSON

<span style="color: green;">INFO</span>:     Waiting for application startup.
<span style="color: green;">INFO</span>:     Application startup complete.
```

</div>

**SANGAT disarankan** agar kamu menulis atau menyalin kode, mengubahnya dan menjalankannya secara lokal.

    return {"Hello": "World"}


@app.get("/items/{item_id}")
def read_item(item_id: int, q: Union[str, None] = None):
    return {"item_id": item_id, "q": q}
```

Jika kode anda menggunakan `async` / `await`, gunakan `async def`:

```Python hl_lines="9  14"
