/// note | Hinweis

Der Befehl `uvicorn main:app` bezieht sich auf:

* `main`: die Datei `main.py` (das Python-„Modul“).
* `app`: das Objekt, das innerhalb von `main.py` mit der Zeile `app = FastAPI()` erstellt wurde.

Es ist äquivalent zu:

```Python
from main import app
```

///

Por exemplo, você poderia ter um arquivo `config.py` com:

{* ../../docs_src/settings/app01_py310/config.py *}

E então usá-lo em um arquivo `main.py`:

{* ../../docs_src/settings/app01_py310/main.py hl[3,11:13] *}

/// tip | Dica

Você também precisaria de um arquivo `__init__.py` como visto em [Aplicações Maiores - Múltiplos Arquivos](../tutorial/bigger-applications.md).

## Call `uvicorn` { #call-uvicorn }

In your FastAPI application, import and run `uvicorn` directly:

### About `__name__ == "__main__"` { #about-name-main }

The main purpose of the `__name__ == "__main__"` is to have some code that is executed when your file is called with:

<div class="termy">

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

</div>

이 `entrypoint`는 `fastapi` 명령어에 다음과 같이 앱을 임포트하라고 알려줍니다:

```python
from main import app
```

코드 구조가 다음과 같다면:

```
.
├── backend
│   ├── main.py
│   ├── __init__.py
```

`entrypoint`를 다음과 같이 설정합니다:

```toml
[tool.fastapi]
entrypoint = "backend.main:app"
```

이는 다음과 동일합니다:

```python
from backend.main import app
```
