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

Zum Beispiel 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] *}

Em muitos casos, sua aplicação FastAPI será maior, e você provavelmente usará tags para separar diferentes grupos de *operações de rota*.

Por exemplo, você poderia ter uma seção para **items** e outra seção para **users**, e elas poderiam ser separadas por tags:

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