for executing the loop body once.
After each successive loop iteration, <code>yield</code> returns true
and may be called again to continue the loop.
As long as the loop body does not terminate, the "range" clause will continue
to generate iteration values this way for each <code>yield</code> call until
<code>f</code> returns.
If the loop body terminates (such as by a <code>break</code> statement),

# Request Body { #request-body }

Cuando necesitas enviar datos desde un cliente (digamos, un navegador) a tu API, los envías como un **request body**.

Un **request** body es un dato enviado por el cliente a tu API. Un **response** body es el dato que tu API envía al cliente.

并且，还会用于需要它们的每个*路径操作*的 API 文档中：

## 编辑器支持 { #editor-support }

在编辑器中，函数内部你会在各处得到类型提示与补全（如果接收的不是 Pydantic 模型，而是 `dict`，就不会有这样的支持）：

还支持检查错误的类型操作：

这并非偶然，整个框架都是围绕这种设计构建的。

也會用於每個需要它們的*路徑操作*內的 API 文件：

## 編輯器支援 { #editor-support }

在編輯器裡、於你的函式中，你會在各處獲得型別提示與自動完成（如果你接收的是 `dict` 而不是 Pydantic 模型，就不會有這些）：

你也會獲得對不正確型別操作的錯誤檢查：

這不是偶然，整個框架就是圍繞這個設計而建。

# Request Body { #request-body }

Bir client'ten (örneğin bir tarayıcıdan) API'nize veri göndermeniz gerektiğinde, bunu **request body** olarak gönderirsiniz.

Bir **request** body, client'in API'nize gönderdiği veridir. Bir **response** body ise API'nizin client'e gönderdiği veridir.

# Request Body { #request-body }

When you need to send data from a client (let's say, a browser) to your API, you send it as a **request body**.

A **request** body is data sent by the client to your API. A **response** body is the data your API sends to the client.

하지만 타입 어노테이션을 추가하면 편집기가 더 나은 지원을 제공하고 오류를 감지할 수 있습니다.
