## `APIRouter` { #apirouter }

Vamos supor que o arquivo dedicado a lidar apenas com usuários seja o submódulo em `/app/routers/users.py`.

Você quer manter as *operações de rota* relacionadas aos seus usuários separadas do restante do código, para mantê-lo organizado.

Mas ele ainda faz parte da mesma aplicação/web API **FastAPI** (faz parte do mesmo "pacote Python").

   * returns the elements in the order they are returned by the collection's iterator. The returned
   * array is "safe" in that no references to it are maintained by the collection. The caller is
   * thus free to modify the returned array.
   *
   * <p>This method assumes that the collection size doesn't change while the method is running.
   *
   * <p>TODO(kevinb): support concurrently modified collections?

-   Different Python versions
-   Linux, MacOS, and Windows machines (these pool definitions are internal)
-   x86 and arm64
-   CPU-only, or with NVIDIA CUDA support (Linux only), or with TPUs

## How to Test Your Changes to TensorFlow

You may check how your changes will affect TensorFlow by:

1. Creating a PR and observing the presubmit test results
2. Running the CI scripts locally, as explained below

Y dentro de eso creo un directorio por proyecto.

<div class="termy">

```console
// Ve al directorio principal
$ cd
// Crea un directorio para todos tus proyectos de código
$ mkdir code
// Entra en ese directorio de código
$ cd code
// Crea un directorio para este proyecto
$ mkdir awesome-project
// Entra en ese directorio del proyecto
$ cd awesome-project
```

#### Retorne membros de enumeração { #return-enumeration-members }

Você pode retornar *membros de enum* da sua *operação de rota*, até mesmo aninhados em um corpo JSON (por exemplo, um `dict`).

Eles serão convertidos para seus valores correspondentes (strings neste caso) antes de serem retornados ao cliente:

{* ../../docs_src/path_params/tutorial005_py310.py hl[18,21,23] *}

No seu cliente, você receberá uma resposta JSON como:

```JSON

       * requireNonNull is safe because:
       *
       * - columnIterator started off pointing to an empty iterator, so we must have entered the
       *   `if` body above at least once. Thus, if we got this far, that `if` body initialized
       *   rowEntry at least once.
       *
       * - The only case in which rowEntry is cleared (during remove() below) happens only if the

         * *non*-nullable, even when they are declared as `Foo?`.
