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:

```Python
from myapp import app
```

#### より詳しい説明

ファイルの名前が `myapp.py` だとします。

以下の様に実行する場合:

<div class="termy">

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

</div>

Pythonによって自動的に作成されたファイル内の内部変数 `__name__` は、値として文字列 `"__main__"` を持ちます。

なので、以下:

```Python
    uvicorn.run(app, host="0.0.0.0", port=8000)
```

は実行されます。
