### Adım 2: Bir `FastAPI` "Örneği" Oluşturalım

```Python hl_lines="3"
{!../../../docs_src/first_steps/tutorial001.py!}
```

Burada `app` değişkeni `FastAPI` sınıfının bir örneği olacaktır.

Bu, tüm API'yı oluşturmak için ana etkileşim noktası olacaktır.

Bu `app` değişkeni, `uvicorn` komutunda atıfta bulunulan değişkenin ta kendisidir.

             * the activated profiles can cause repo declarations to be lost which in turn will result in artifact
             * resolution failures, in particular when using the enhanced local repo which guards access to local files
             * based on the configured remote repos.
             */
            MavenSession session = legacySupport.getSession();
            if (session != null) {

     * which it is guaranteed that it can never become healthy.
     */
    final Monitor.Guard awaitHealthGuard = new AwaitHealthGuard();

    @WeakOuter
    final class AwaitHealthGuard extends Monitor.Guard {
      AwaitHealthGuard() {
        super(ServiceManagerState.this.monitor);
      }

      @Override

```

</div>

Si creas un app como:

```Python hl_lines="3"
{!../../../docs_src/first_steps/tutorial002.py!}
```

y lo guardas en un archivo `main.py`, entonces ejecutarías `uvicorn` así:

<div class="termy">

```console
$ uvicorn main:my_awesome_api --reload

      ],
      "msg": "Input should be a valid integer, unable to parse string as an integer",
      "input": "foo",
      "url": "https://errors.pydantic.dev/2.1/v/int_parsing"
    }
  ]
}
```

Çünkü burada `item_id` yol parametresi `int` tipinde bir değer beklerken `"foo"` yani `string` tipinde bir değer almıştı.

#### General guidelines and philosophy for contribution

*   Include unit tests when you contribute new features, as they help to a)
    prove that your code works correctly, and b) guard against future breaking
    changes to lower the maintenance cost.
*   Bug fixes also generally require unit tests, because the presence of bugs
    usually indicates insufficient test coverage.
