Notice that the error also clearly states exactly the point where the validation didn't pass.

This is incredibly helpful while developing and debugging code that interacts with your API.

## Documentation

```

El `@app.get("/")` le dice a **FastAPI** que la función que tiene justo debajo está a cargo de manejar los requests que van a:

* el path `/`
* usando una <abbr title="an HTTP GET method">operación <code>get</code></abbr>

/// info | Información sobre `@decorator`

Esa sintaxis `@algo` se llama un "decorador" en Python.

{!> ../../docs_src/dependencies/tutorial001.py!}
```

////

Aber dann haben wir ein `dict` im Parameter `commons` der *Pfadoperation-Funktion*.

Und wir wissen, dass Editoren nicht viel Unterstützung (wie etwa Code-Vervollständigung) für `dict`s bieten können, weil sie ihre Schlüssel- und Werttypen nicht kennen.

Das können wir besser machen ...

## Was macht eine Abhängigkeit aus

```

O `@app.get("/")` diz ao **FastAPI** que a função logo abaixo é responsável por tratar as requisições que vão para:

* a rota `/`
* usando o  <abbr title="o método HTTP GET">operador <code>get</code></abbr>

/// info | "`@decorador`"

Essa sintaxe `@alguma_coisa` em Python é chamada de "decorador".

Você o coloca em cima de uma função. Como um chapéu decorativo (acho que é daí que vem o termo).

Вам редко нужно будет возвращаться к документации.

All this might not seem as useful with these simple examples.

But you will see how useful it is in the chapters about **security**.

And you will also see the amounts of code it will save you.

HTTP-Header sind außerdem unabhängig von Groß-/Kleinschreibung, darum können Sie sie mittels der Standard-Python-Schreibweise deklarieren (auch bekannt als "snake_case").

Sie können also `user_agent` schreiben, wie Sie es normalerweise in Python-Code machen würden, statt etwa die ersten Buchstaben groß zu schreiben, wie in `User_Agent`.
