#### Unpacking a `dict` { #unpacking-a-dict }

If we take a `dict` like `user_dict` and pass it to a function (or class) with `**user_dict`, Python will "unpack" it. It will pass the keys and values of the `user_dict` directly as key-value arguments.

So, continuing with the `user_dict` from above, writing:

```Python

## 前一個範例中的 `dict` { #a-dict-from-the-previous-example }

在前一個範例中，我們從相依項（"dependable"）回傳了一個 `dict`：

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[9] *}

但接著我們在路徑操作函式（*path operation function*）的參數 `commons` 中取得的是一個 `dict`。

而我們知道，編輯器對 `dict` 無法提供太多輔助（例如自動完成），因為它無法預先知道其中的鍵與值的型別。

我們可以做得更好...

## 什麼算是相依性 { #what-makes-a-dependency }

到目前為止，你看到的相依性都是宣告成函式。

但那不是宣告相依性的唯一方式（雖然那大概是最常見的）。
