## Advanced description from docstring { #advanced-description-from-docstring }

You can limit the lines used from the docstring of a *path operation function* for OpenAPI.

Adding an `\f` (an escaped "form feed" character) causes **FastAPI** to truncate the output used for OpenAPI at this point.

It won't show up in the documentation, but other tools (such as Sphinx) will be able to use the rest.

     *
     * This method removes characters that are not allowed in XML documents
     * according to the XML 1.0 specification. Valid characters include:
     * - Tab (0x9)
     * - Line feed (0xA)
     * - Carriage return (0xD)
     * - Any character between 0x20 and 0xD7FF
     * - Any character between 0xE000 and 0xFFFD
     * - Any character between 0x10000 and 0x10FFFF
     *

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 (wie z. B. Sphinx) können den Rest verwenden.

## Расширенное описание из docstring { #advanced-description-from-docstring }

Вы можете ограничить количество строк из docstring *функции-обработчика пути*, используемых для OpenAPI.

Добавление `\f` (экранированного символа «form feed») заставит **FastAPI** обрезать текст, используемый для OpenAPI, в этой точке.

Эта часть не попадёт в документацию, но другие инструменты (например, Sphinx) смогут использовать остальное.

        # truncate description text to the content preceding the first "form feed"
