## Variable de Entorno `PATH` { #path-environment-variable }

Hay una variable de entorno **especial** llamada **`PATH`** que es utilizada por los sistemas operativos (Linux, macOS, Windows) para encontrar programas a ejecutar.

Der einzige Unterschied besteht darin, dass die `HTTPException` von **FastAPI** beliebige JSON-konvertierbare Daten für das `detail`-Feld akzeptiert, während die `HTTPException` von Starlette nur Strings dafür akzeptiert.

Sie können also weiterhin die `HTTPException` von **FastAPI** wie üblich in Ihrem Code auslösen.

Nota que el valor que tu función recibió (y devolvió) es `3`, como un `int` de Python, no un string `"3"`.

Entonces, con esa declaración de tipo, **FastAPI** te ofrece <abbr title="convertir el string que viene de un request HTTP en datos de Python">"parsing"</abbr> automático de request.
