Например, у вас может быть файл `config.py` со следующим содержимым:

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

А затем использовать его в файле `main.py`:

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

/// tip | Совет

Вам также понадобится файл `__init__.py`, как в разделе [Большие приложения — несколько файлов](../tutorial/bigger-applications.md).

///

```

</div>

/// note

指令 `uvicorn main:app` 指的是：

* `main`：檔案 `main.py`（Python「模組」）。
* `app`：在 `main.py` 中以 `app = FastAPI()` 建立的物件。

等同於：

```Python
from main import app
```

///

其他 ASGI 伺服器也有類似的指令，詳見各自的文件。

/// warning

Uvicorn 與其他伺服器支援 `--reload` 選項，對開發期間很有幫助。

O arquivo `main.py` teria:

{* ../../docs_src/async_tests/app_a_py310/main.py *}

O arquivo `test_main.py` teria os testes para para o arquivo `main.py`, ele poderia ficar assim:

{* ../../docs_src/async_tests/app_a_py310/test_main.py *}

## Executá-lo { #run-it }

Örneğin `config.py` adında bir dosyanız şu şekilde olabilir:

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

Ve ardından bunu `main.py` dosyasında kullanabilirsiniz:

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

/// tip | İpucu

[Daha Büyük Uygulamalar](bigger-applications.md)'te anlatılan şekilde bir dosya yapınız olduğunu varsayalım:

```
.
├── app
│   ├── __init__.py
│   └── main.py
```

`main.py` dosyasında **FastAPI** uygulamanız bulunuyor olsun:

{* ../../docs_src/app_testing/app_a_py310/main.py *}
