```

would mean:

* Starting in the same package that this module (the file `app/routers/items.py`) lives in (the directory `app/routers/`)...
* find the module `dependencies` (an imaginary file at `app/routers/dependencies.py`)...
* and from it, import the function `get_token_header`.

But that file doesn't exist, our dependencies are in a file at `app/dependencies.py`.

* Check if you can understand what is the **purpose** and use case of the person asking.

* Then check if the question (the vast majority are questions) is **clear**.

* In many cases the question asked is about an imaginary solution from the user, but there might be a **better** one. If you can understand the problem and use case better, you might be able to suggest a better **alternative solution**.

do exactly this.

A read of an array, struct, or complex number
may be implemented as a read of each individual sub-value
(array element, struct field, or real/imaginary component),
in any order.
Similarly, a write of an array, struct, or complex number
may be implemented as a write of each individual sub-value,
in any order.

### Incluir um `APIRouter` com um `prefix` personalizado, `tags`, `responses` e `dependencies`

Agora, vamos imaginar que sua organização lhe deu o arquivo `app/internal/admin.py`.

Ele contém um `APIRouter` com algumas *operações de rota* de administração que sua organização compartilha entre vários projetos.

**Concurrencia** y **paralelismo** ambos se relacionan con "diferentes cosas sucediendo más o menos al mismo tiempo".

Pero los detalles entre *concurrencia* y *paralelismo* son bastante diferentes.

Para ver la diferencia, imagina la siguiente historia sobre hamburguesas:

### Hamburguesas Concurrentes

Vas con tu crush a conseguir comida rápida, te pones en fila mientras el cajero toma los pedidos de las personas frente a ti. 😍

{* ../../docs_src/python_types/tutorial001.py hl[2] *}

### Edítalo

Es un programa muy simple.

Pero ahora imagina que lo escribieras desde cero.

En algún momento habrías empezado la definición de la función, tenías los parámetros listos...

Pero luego tienes que llamar "ese método que convierte la primera letra a mayúscula".

```

würde bedeuten:

* Beginnend im selben Package, in dem sich dieses Modul (die Datei `app/routers/items.py`) befindet (das Verzeichnis `app/routers/`) ...
* finde das Modul `dependencies` (eine imaginäre Datei unter `app/routers/dependencies.py`) ...
* und importiere daraus die Funktion `get_token_header`.

Aber diese Datei existiert nicht, unsere Abhängigkeiten befinden sich in einer Datei unter `app/dependencies.py`.
