### 編寫自己的非同步程式碼 { #write-your-own-async-code }

Starlette（和 **FastAPI**）是基於 [AnyIO](https://anyio.readthedocs.io/en/stable/) 實作的，這使得它們與 Python 標準函式庫 [asyncio](https://docs.python.org/3/library/asyncio-task.html) 和 [Trio](https://trio.readthedocs.io/en/stable/) 相容。

特別是，你可以直接使用 [AnyIO](https://anyio.readthedocs.io/en/stable/) 來處理更複雜的並行使用案例，這些案例需要你在自己的程式碼中使用更高階的模式。

### 编写自己的异步代码 { #write-your-own-async-code }

Starlette （和 **FastAPI**） 是基于 [AnyIO](https://anyio.readthedocs.io/en/stable/) 实现的，这使得它们可以兼容 Python 的标准库 [asyncio](https://docs.python.org/3/library/asyncio-task.html) 和 [Trio](https://trio.readthedocs.io/en/stable/)。

特别是，你可以直接使用 [AnyIO](https://anyio.readthedocs.io/en/stable/) 来处理高级的并发用例，这些用例需要在自己的代码中使用更高级的模式。

from .routers import items, users
```

第二个版本是「绝对导入」：

```Python
from app.routers import items, users
```

要了解有关 Python 包和模块的更多信息，请查阅[关于 Modules 的 Python 官方文档](https://docs.python.org/3/tutorial/modules.html)。

### 避免名称冲突 { #avoid-name-collisions }

我们将直接导入 `items` 子模块，而不是仅导入其 `router` 变量。

这是因为我们在 `users` 子模块中也有另一个名为 `router` 的变量。

如果我们一个接一个地导入，例如：

```Python

Some upgrade methods might upgrade etcd from 3.0 to 3.1 automatically when you upgrade from Kubernetes 1.8, unless you specify otherwise. Because [etcd does not support downgrading](https://coreos.com/etcd/docs/latest/upgrades/upgrade_3_1.html), you'll need to either remain on etcd 3.1 or restore from a backup if you want to downgrade back to Kubernetes 1.8.
