### Étape 5 : retourner le contenu

{* ../../docs_src/first_steps/tutorial001.py hl[8] *}

Vous pouvez retourner un dictionnaire (`dict`), une liste (`list`), des valeurs seules comme des chaines de caractères (`str`) et des entiers (`int`), etc.

Vous pouvez aussi retourner des models **Pydantic** (qui seront détaillés plus tard).

	LatestOnly   bool                     // returns only latest versions for all matching objects
	AskDisks     string                   // dictates how many disks are being listed
	VersionsSort WalkVersionsSortOrder    // sort order for versions of the same object; default: Ascending order in ModTime
	Limit        int                      // maximum number of items, 0 means no limit
}

					s.walkReadMu.Unlock()

				diskHealthCheckOK(ctx, err)
				if err != nil {
					// It is totally possible that xl.meta was overwritten
					// while being concurrently listed at the same time in
					// such scenarios the 'xl.meta' might get truncated
					if !IsErrIgnored(err, io.EOF, io.ErrUnexpectedEOF) {
						internalLogOnceIf(ctx, err, "metacache-walk-read-metadata")
					}

		// if we don't have a subfolder directory listed.
	}
	err := w.AddFS(writeTestsToFS(tests))
	if err != nil {
		t.Fatal(err)
	}
	if err := w.Close(); err != nil {
		t.Fatal(err)
	}

  /**
   * Starts the server on the loopback interface for the given port.
   *
   * @param port the port to listen to, or 0 for any available port. Automated tests should always
   * use port 0 to avoid flakiness when a specific port is unavailable.

Aber standardmäßig **„funktioniert einfach alles“**.

### Validierung

* Validierung für die meisten (oder alle?) Python-**Datentypen**, hierzu gehören:
    * JSON Objekte (`dict`).
    * JSON Listen (`list`), die den Typ ihrer Elemente definieren.
    * Strings (`str`) mit definierter minimaler und maximaler Länge.
    * Zahlen (`int`, `float`) mit Mindest- und Maximal-Werten, usw.

        sdf.setCalendar(cal);

        dirents = dir.listFiles();
        if (log.isDebugEnabled()) {
            log.debug(dirents.length + " items listed");
        }
        sorted = new LinkedList<>();
        fmt = req.getParameter("fmt");
        if (fmt == null) {
            fmt = "col";
        }
        sort = 0;

 * {@link ImmutableList}) instead of the general collection interface type (such as {@link List}).
 * This communicates to your callers all of the semantic guarantees listed above, which is almost
 * always very useful information.
 *
 * <p>On the other hand, a <i>parameter</i> type of {@link ImmutableList} is generally a nuisance to
