//// tab | `venv`

你可以使用 Python 自帶的 `venv` 模組來建立一個虛擬環境。

<div class="termy">

```console
$ python -m venv .venv
```

</div>

/// details | 上述命令的含義

* `python`: 使用名為 `python` 的程式
* `-m`: 以腳本的方式呼叫一個模組，我們將告訴它接下來使用哪個模組

//// tab | `uv`

When the _namespace_ format is used, MinIO synchronizes objects in the bucket with documents in the index. For each event in the MinIO, the server creates a document with the bucket and object name from the event as the document ID. Other details of the event are stored in the body of the document. Thus if an existing object is over-written in MinIO, the corresponding document in the Elasticsearch index is updated. If an object is deleted, the corresponding document is deleted from the index....

## Integrierte Middleware { #integrated-middlewares }

**FastAPI** enthält mehrere Middlewares für gängige Anwendungsfälle. Wir werden als Nächstes sehen, wie man sie verwendet.

//// tab | `venv`

Para criar um ambiente virtual, você pode usar o módulo `venv` que vem com o Python.

<div class="termy">

```console
$ python -m venv .venv
```

</div>

/// details | O que esse comando significa

* `python`: usa o programa chamado `python`
* `-m`: chama um módulo como um script, nós diremos a ele qual módulo vem em seguida

## Einen `websocket` erstellen { #create-a-websocket }

Erstellen Sie in Ihrer **FastAPI**-Anwendung einen `websocket`:

{* ../../docs_src/websockets_/tutorial001_py310.py hl[1,46:47] *}

/// note | Technische Details

Sie könnten auch `from starlette.websockets import WebSocket` verwenden.

**FastAPI** stellt den gleichen `WebSocket` direkt zur Verfügung, als Annehmlichkeit für Sie, den Entwickler. Er kommt aber direkt von Starlette.

Mas, seguindo os passos acima, ele será capaz de fazer algumas otimizações de performance.

## Detalhes Técnicos { #technical-details }

Versões modernas de Python têm suporte para **"código assíncrono"** usando algo chamado **"corrotinas"**, com sintaxe **`async` e `await`**.

Vamos ver aquela frase por partes nas seções abaixo:

```CSS hl_lines="4"
{!../../docs_src/templates/static/styles.css!}
```

그리고 `StaticFiles`를 사용하고 있으므로, 해당 CSS 파일은 **FastAPI** 애플리케이션에서 `/static/styles.css` URL로 자동 제공됩니다.
