* フレームワークによってすべて**自動的に処理**されます。
* すべての依存関係はリクエストからのデータを要請できて、**path operationsの制約と自動ドキュメンテーションを拡張できます**。
* 依存関係で定義された *path operation* パラメータも**自動検証**が可能です。
* 複雑なユーザー認証システム、**データベース接続**などのサポート
* **データベース、フロントエンドなどに対する妥協はありません**。それらすべてと簡単に統合できます。

### 無制限の「プラグイン」

他の方法では、それらを必要とせず、必要なコードをインポートして使用します。

統合は非常に簡単に使用できるように設計されており（依存関係を用いて）、*path operations* で使用されているのと同じ構造と構文を使用して、2行のコードでアプリケーションの「プラグイン」を作成できます。

  // For the time being we are OK with the problem discussed above since it requires a caller to
  // introduce a very specific kind of data-race. And given the other operations performed by these
  // methods that involve volatile read/write operations, in practice there is no issue. Also, the
  // way in such a visibility issue would surface is most likely as a failure of cancel() to

We can **read** a single hero:

{* ../../docs_src/sql_databases/tutorial002_an_py310.py ln[75:80] hl[77] *}

### Update a Hero with `HeroUpdate`

We can **update a hero**. For this we use an HTTP `PATCH` operation.

     * read operations anyway:
     *
     * - All (unsynchronized) read operations must first read the "count" field, and should not
     * look at table entries if it is 0.
     *
     * - All (synchronized) write operations should write to the "count" field after structurally
     * changing any bin. The operations must not take any action that could even momentarily

Kullanım şekli oldukça basit. Örneğin bir `GET` isteği yapmak için aşağıdaki yeterli:

```Python
response = requests.get("http://example.com/some/url")
```

Bunun FastAPI'deki API <abbr title="Yol İşlemi: Path Operation">*yol işlemi*</abbr> şöyle görünür:

```Python hl_lines="1"
@app.get("/some/url")
def read_url():
    return {"message": "Hello World!"}
```
