Visual Studio CodeやPyCharmなどを使用して、エディター上でデバッガーと連携できます。

## `uvicorn` の実行

FastAPIアプリケーション上で、`uvicorn` を直接インポートして実行します:

{* ../../docs_src/debugging/tutorial001.py hl[1,15] *}

### `__name__ == "__main__"` について

`__name__ == "__main__"` の主な目的は、ファイルが次のコマンドで呼び出されたときに実行されるコードを用意することです:

<div class="termy">

```console
$ python myapp.py
```

</div>

ただし、次のように、別のファイルからインポートされるときには呼び出されません:
