## FastAPI-Anwendung mit Tags

In vielen Fällen wird Ihre FastAPI-Anwendung größer sein und Sie werden wahrscheinlich Tags verwenden, um verschiedene Gruppen von *Pfadoperationen* zu separieren.

Beispielsweise könnten Sie einen Abschnitt für **Items (Artikel)** und einen weiteren Abschnitt für **Users (Benutzer)** haben, und diese könnten durch Tags getrennt sein:

{* ../../docs_src/generate_clients/tutorial002_py39.py hl[21,26,34] *}

      seenExceptions = newHashSet();
      addInitialException(seenExceptions);
    }
    return seenExceptions;
  }

  abstract void addInitialException(Set<Throwable> seen);

  final int decrementRemainingAndGet() {
    return --remaining;
  }

  final void clearSeenExceptions() {
    seenExceptions = null;
  }
