Por exemplo, [você pode utilizar `with` para ler um arquivo](https://docs.python.org/3/tutorial/inputoutput.html#reading-and-writing-files):

```Python
with open("./somefile.txt") as f:
    contents = f.read()
    print(contents)
```

Por baixo dos panos, o código `open("./somefile.txt")` cria um objeto que é chamado de "Gerenciador de Contexto".

///

### `.env` 文件 { #the-env-file }

你可以有一个 `.env` 文件，内容如下：

```bash
ADMIN_EMAIL="******@****.***"
APP_NAME="ChimichangApp"
```

### 从 `.env` 中读取设置 { #read-settings-from-env }

然后更新 `config.py`：

{* ../../docs_src/settings/app03_an_py310/config.py hl[9] *}
