OpenAPI JSON을 `openapi.json` 파일로 다운로드한 뒤, 아래와 같은 스크립트로 **접두사 태그를 제거**할 수 있습니다:

//// tab | Node.js

```Javascript

이렇게 하면 operation ID가 `items-get_items` 같은 형태에서 `get_items`로 변경되어, 클라이언트 생성기가 더 단순한 메서드 이름을 생성할 수 있습니다.

This means that `item` could be an `int` or a `str`.

#### Possibly `None` { #possibly-none }

You can declare that a value could have a type, like `str`, but that it could also be `None`.

OpenAPI の JSON を `openapi.json` として保存し、次のようなスクリプトで**そのタグのプレフィックスを除去**できます:

{* ../../docs_src/generate_clients/tutorial004_py310.py *}

//// tab | Node.js

```Javascript
{!> ../../docs_src/generate_clients/tutorial004.js!}
```

////

これにより operation ID は `items-get_items` のような形から単なる `get_items` に置き換わり、クライアントジェネレータはより簡潔なメソッド名を生成できます。

但对于生成的客户端，我们可以在生成之前**修改** OpenAPI 的操作 ID，只是为了让方法名更美观、更**简洁**。

我们可以把 OpenAPI JSON 下载到 `openapi.json` 文件中，然后用如下脚本**移除这个标签前缀**：

{* ../../docs_src/generate_clients/tutorial004_py310.py *}

//// tab | Node.js

```Javascript
{!> ../../docs_src/generate_clients/tutorial004.js!}
```

////

这样，操作 ID 会从 `items-get_items` 之类的名字重命名为 `get_items`，从而让客户端生成器生成更简洁的方法名。

```Python hl_lines="1"
{!> ../../docs_src/python_types/tutorial008b_py310.py!}
```

這表示 `item` 可以是 `int` 或 `str`。

#### 可能為 `None` { #possibly-none }

你可以宣告某個值可以是某個型別（例如 `str`），但它也可能是 `None`。

//// tab | Python 3.10+

```Python hl_lines="1"
{!> ../../docs_src/python_types/tutorial009_py310.py!}
```

////

使用 `str | None` 而不是單純的 `str`，可以讓編輯器幫你偵測錯誤，例如你以為某個值一定是 `str`，但它其實也可能是 `None`。
