`__name__ == "__main__"`의 주요 목적은 다음과 같이 파일이 호출될 때 실행되는 일부 코드를 갖는 것입니다.

<div class="termy">

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

</div>

그러나 다음과 같이 다른 파일을 가져올 때는 호출되지 않습니다.

```Python
from myapp import app
```

#### 추가 세부사항

파일 이름이 `myapp.py`라고 가정해 보겠습니다.

다음과 같이 실행하면

<div class="termy">

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

</div>
