To add a function that should be run before the application starts, declare it with the event `"startup"`:

{* ../../docs_src/events/tutorial001.py hl[8] *}

In this case, the `startup` event handler function will initialize the items "database" (just a `dict`) with some values.

You can add more than one event handler function.

And your application won't start receiving requests until all the `startup` event handlers have completed.

## Alias-Parameter

Stellen Sie sich vor, der Parameter soll `item-query` sein.

Wie in:

```
http://127.0.0.1:8000/items/?item-query=foobaritems
```

Aber `item-query` ist kein gültiger Name für eine Variable in Python.

Am ähnlichsten wäre `item_query`.

Aber Sie möchten dennoch exakt `item-query` verwenden.

대괄호 안의 내부 타입은 "타입 매개변수(type paramters)"라고 합니다.

이번 예제에서는 `str`이 `List`에 들어간 타입 매개변수 입니다.

///

이는 "`items`은 `list`인데, 배열에 들어있는 아이템 각각은 `str`이다"라는 뜻입니다.

이렇게 함으로써, 에디터는 배열에 들어있는 아이템을 처리할때도 도움을 줄 수 있게 됩니다:

<img src="/img/python-types/image05.png">

타입이 없으면 이건 거의 불가능이나 다름 없습니다.

변수 `item`은 `items`의 개별 요소라는 사실을 알아두세요.

그리고 에디터는 계속 `str`라는 사실을 알고 도와줍니다.

#### `Tuple`과 `Set`
