    Interceptors that rewrite or replace the request body may now inadvertently interfere with
    duplex request bodies. Such interceptors should check `RequestBody.isDuplex()` and avoid
    accessing the request body when it is.

    Duplex calls require HTTP/2. If HTTP/1 is established instead the duplex call will fail. The
    most common use of duplex calls is [gRPC][grpc_http2].

    private set

  // These properties are guarded by [lock]. They are typically only accessed by the thread executing
  // the call, but they may be accessed by other threads for duplex requests.

  /** True if this call still has a request body open. */
  private var requestBodyOpen = false

  /** True if this call still has a response body open. */
  private var responseBodyOpen = false

          exchange.responseHeadersStart()
          invokeStartEvent = false
        }
        if (responseBuilder == null) {
          if (requestBody.isDuplex()) {
            // Prepare a duplex body so that the application can send a request body later.
            exchange.flushRequest()
            val bufferedRequestBody = exchange.createRequestBody(request, true).buffer()

#### 🔢 & ⚒

👆 🔜 🎏 📣 `tuple`Ⓜ & `set`Ⓜ:

=== "🐍 3️⃣.6️⃣ & 🔛"

    ```Python hl_lines="1  4"
    {!> ../../../docs_src/python_types/tutorial007.py!}
    ```

=== "🐍 3️⃣.9️⃣ & 🔛"

    ```Python hl_lines="1"
    {!> ../../../docs_src/python_types/tutorial007_py39.py!}
    ```

👉 ⛓:

* 🔢 `items_t` `tuple` ⏮️ 3️⃣ 🏬, `int`, ➕1️⃣ `int`, & `str`.

注意，变量 `item` 是列表 `items` 中的元素之一。

而且，编辑器仍然知道它是一个 `str`，并为此提供了支持。

#### 元组和集合

声明 `tuple` 和 `set` 的方法也是一样的：

```Python hl_lines="1  4"
{!../../../docs_src/python_types/tutorial007.py!}
```

这表示：

* 变量 `items_t` 是一个 `tuple`，其中的前两个元素都是 `int` 类型, 最后一个元素是 `str` 类型。
* 变量 `items_s` 是一个 `set`，其中的每个元素都是 `bytes` 类型。

#### 字典

定义 `dict` 时，需要传入两个子类型，用逗号进行分隔。
