## Motivation { #motivation }

Commençons par un exemple simple :

{* ../../docs_src/python_types/tutorial001_py310.py *}

Exécuter ce programme affiche :

```
John Doe
```

La fonction fait ce qui suit :

* Prend un `first_name` et un `last_name`.
* Convertit la première lettre de chacun en majuscule avec `title()`.

                        }
                    }
                }

                @Override
                public void onChunk(final String content, final boolean done) {
                    try {
                        if (content != null && !content.isEmpty()) {
                            sendSseEvent(writer, "chunk", Map.of("content", content));
                        }

    super(new TreeMap<R, Map<C, V>>(rowComparator), new Factory<C, V>(columnComparator));
    this.columnComparator = columnComparator;
  }

  // TODO(jlevy): Move to StandardRowSortedTable?

  /**
   * Returns the comparator that orders the rows. With natural ordering, {@link Ordering#natural()}
   * is returned.

Вот некоторые элементы, обёрнутые в HTML-элементы "abbr" (часть выдумана):

`data` 字段始终会被编码为 JSON。你可以传入任何可被序列化为 JSON 的值，包括 Pydantic 模型。

## 原始数据 { #raw-data }

如果你需要发送**不**进行 JSON 编码的数据，请使用 `raw_data` 而不是 `data`。

这对于发送预格式化文本、日志行或特殊的 <dfn title="用于指示特殊条件或状态的值">"哨兵"</dfn> 值（例如 `[DONE]`）很有用。

{* ../../docs_src/server_sent_events/tutorial003_py310.py hl[17] *}

/// note | 注意

`data` 和 `raw_data` 是互斥的。每个 `ServerSentEvent` 上只能设置其中一个。
