## Description avancée de docstring

Vous pouvez limiter le texte utilisé de la docstring d'une *fonction de chemin* qui sera affiché sur OpenAPI.

L'ajout d'un `\f` (un caractère d'échappement "form feed") va permettre à **FastAPI** de tronquer la sortie utilisée pour OpenAPI à ce stade.

Il n'apparaîtra pas dans la documentation, mais d'autres outils (tel que Sphinx) pourront utiliser le reste.

```Python hl_lines="19-29"

## Fortgeschrittene Beschreibung mittels Docstring

Sie können die verwendeten Zeilen aus dem Docstring einer *Pfadoperation-Funktion* einschränken, die für OpenAPI verwendet werden.

Das Hinzufügen eines `\f` (ein maskiertes „Form Feed“-Zeichen) führt dazu, dass **FastAPI** die für OpenAPI verwendete Ausgabe an dieser Stelle abschneidet.

Sie wird nicht in der Dokumentation angezeigt, aber andere Tools (z. B. Sphinx) können den Rest verwenden.

- extension artifact missing
- artifact metadata retrieval problem
- version range violation
- circular dependency
- artifact missing
- artifact retrieval exception
- md5 checksum doesn't match for local artifact, need to redownload this
- POM doesn't exist for a goal that requires one
- parent POM missing (in both the repository + relative path)
- component not found

Plugins:
- plugin metadata missing

                if ( !append && this.smb2 ) {
                    // no open option for truncating, need to truncate the file
                    Smb2SetInfoRequest treq = new Smb2SetInfoRequest(th.getConfig(), fh.getFileId());
                    treq.setFileInformation(new FileEndOfFileInformation(0));

### Import typing's `List`

In Python 3.9 and above you can use the standard `list` to declare these type annotations as we'll see below. 💡

But in Python versions before 3.9 (3.6 and above), you first need to import `List` from standard Python's `typing` module:

```Python hl_lines="1"
{!> ../../docs_src/body_nested_models/tutorial002.py!}
```

### Declare a `list` with a type parameter

						}
						recDst = recDst[:len(record)]
						copy(recDst, record)
						all = append(all, recDst)
					}
				}()
				if err != nil {
					in.err = err
				}
				// We don't need the input any more.
				//nolint:staticcheck // SA6002 Using pointer would allocate more since we would have to copy slice header before taking a pointer.
				r.bufferPool.Put(in.input)
				in.input = nil
				in.dst <- all

			continue
		}
		switch header {
		case "expect":
			// Golang http server strips off 'Expect' header, if the
			// client sent this as part of signed headers we need to
			// handle otherwise we would see a signature mismatch.
			// `aws-cli` sets this as part of signed headers.
			//
			// According to
			// http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.20
