## Déprécier un *chemin d'accès* { #deprecate-a-path-operation }

Si vous devez marquer un *chemin d'accès* comme <dfn title="obsolète, il est recommandé de ne pas l'utiliser">déprécié</dfn>, sans pour autant le supprimer, passez le paramètre `deprecated` :

{* ../../docs_src/path_operation_configuration/tutorial006_py310.py hl[16] *}

Il sera clairement marqué comme déprécié dans les documents interactifs :

{* ../../docs_src/custom_response/tutorial007_py310.py hl[3,16] *}

/// note | 技術詳細

`async` タスクは `await` に到達したときにのみキャンセルできます。`await` がない場合、ジェネレータ（`yield` を持つ関数）は適切にキャンセルできず、キャンセル要求後も実行が続く可能性があります。

この小さな例では `await` が不要なため、イベントループにキャンセルを処理する機会を与えるために `await anyio.sleep(0)` を追加しています。

これは大きなストリームや無限ストリームではさらに重要になります。

```Python
with open("file.txt") as file:
    file.read()
```

In recent versions of Python, there's also an **async context manager**. You would use it with `async with`:

```Python
async with lifespan(app):
    await do_stuff()
```

with open("file.txt") as file:
    file.read()
```

Em versões mais recentes do Python, há também um **gerenciador de contexto assíncrono**. Você o usaria com `async with`:

```Python
async with lifespan(app):
    await do_stuff()
```
