### 非 async の *path operation 関数* { #non-async-path-operation-functions }

通常の `def` 関数（`async` なし）も使用でき、同様に `yield` を使えます。

イベントループをブロックしないよう、FastAPI が正しく実行されるように調整します。

この場合は関数が async ではないため、適切な戻り値の型は `Iterable[Item]` です:

{* ../../docs_src/server_sent_events/tutorial001_py310.py ln[28:31] hl[29] *}

### 戻り値の型なし { #no-return-type }

戻り値の型を省略することもできます。FastAPI は [`jsonable_encoder`](./encoder.md) を使ってデータを変換し、送信します。
