## 上下文管理器 { #context-managers }

### 什么是“上下文管理器” { #what-are-context-managers }

“上下文管理器”是你可以在 `with` 语句中使用的任意 Python 对象。

例如，[你可以用 `with` 来读取文件](https://docs.python.org/3/tutorial/inputoutput.html#reading-and-writing-files)：

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

在底层，`open("./somefile.txt")` 会创建一个“上下文管理器”对象。

Nous pouvons ensuite tester qu'il est bien utilisé.

   * wakeup</a>. This means that resulting wait is not "uninterruptible" in the normal sense of
   * {@link Uninterruptibles}. Still, this method allows callers to write <a

## Leer un archivo `.env` { #reading-a-env-file }

Si tienes muchas configuraciones que posiblemente cambien mucho, tal vez en diferentes entornos, podría ser útil ponerlos en un archivo y luego leerlos desde allí como si fueran variables de entorno.
