FastAPI transmettra chaque bloc de données à la `StreamingResponse` tel quel ; il n'essaiera pas de le convertir en JSON ni autre chose similaire.

### Fonctions de chemin d'accès non async { #non-async-path-operation-functions }

Vous pouvez également utiliser des fonctions `def` classiques (sans `async`), et utiliser `yield` de la même manière.

    * Si vous connaissez les types Python vous savez utiliser Pydantic.
* Fonctionne bien avec votre **<abbr title="Integrated Development Environment - Environnement de développement intégré: similaire à un éditeur de code">IDE</abbr>/<dfn title="Programme qui vérifie les erreurs de code">linter</dfn>/cerveau** :

      description: Please confirm and check all the following options.
      options:
        - label: I added a very descriptive title here.
          required: true
        - label: I used the GitHub search to find a similar question and didn't find it.
          required: true
        - label: I searched the FastAPI documentation, with the integrated search.
          required: true

            executor.shutdown();
        }
    }

    /**
     * Test watch timeout scenario
     */
    @Test
    void testWatchTimeout() throws Exception {
        // Create a handle that simulates blocking operation
        SmbWatchHandle blockingHandle = new SmbWatchHandle() {
            @Override
            public List<FileNotifyInformation> watch() throws CIFSException {
                try {

Nous pouvons ensuite l'utiliser comme type d'un attribut :

Cela signifie que FastAPI attendrait un corps similaire à :

```JSON

    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2,
    "tags": ["rock", "metal", "bar"],
    "image": {
        "url": "http://example.com/baz.jpg",

          submittingTaskQueue.nextTask = task;
          // requireNonNull(delegate) is safe for reasons similar to requireNonNull(sequencer).
          submittingTaskQueue.nextExecutor = requireNonNull(delegate);
          delegate = null;
        } else {
          // requireNonNull(delegate) is safe for reasons similar to requireNonNull(sequencer).
          Executor localDelegate = requireNonNull(delegate);
          delegate = null;

as stateful containers with local storage (JBOD/JBOF) mapped as persistent local volumes. This architecture enables multi-tenant MinIO, allowing isolation of data between customers.

MinIO also supports multi-cluster, multi-site federation similar to AWS regions and tiers. Using MinIO Information Lifecycle Management (ILM), you can configure data to be tiered between NVMe based hot storage, and HDD based warm storage. All data is encrypted with per-object key.

# Virtual Environments { #virtual-environments }

When you work in Python projects you probably should use a **virtual environment** (or a similar mechanism) to isolate the packages you install for each project.

/// info

If you already know about virtual environments, how to create them and use them, you might want to skip this section. 🤓

///

/// tip

A **virtual environment** is different than an **environment variable**.
