### Étape 2 : créer une "instance" `FastAPI`

```Python hl_lines="3"
{!../../docs_src/first_steps/tutorial001.py!}
```

Ici la variable `app` sera une "instance" de la classe `FastAPI`.

Ce sera le point principal d'interaction pour créer toute votre API.

Cette `app` est la même que celle à laquelle fait référence `uvicorn` dans la commande :

<div class="termy">

```console

	 Todos os utilitários de segurança que se integram com OpenAPI (e na documentação da API automática) herdam de `SecurityBase`, é assim que **FastAPI** pode saber como integrá-los no OpenAPI.

## O que ele faz

Isso foi implementado dessa forma principalmente para permitir que os mesmos objetos fornecidos ("yielded") pelas dependências dentro de tarefas de background fossem reutilizados, por que o código de saída era executado antes das tarefas de background serem finalizadas.

    mockWebServer: MockWebServer,
  ) {
    setUp(protocol, mockWebServer)
    server.enqueue(MockResponse(body = "abc"))
    server.enqueue(MockResponse(body = "def"))

    // Disconnect before the stream is created. A connection is still established!
    val call1 = client.newCall(Request(server.url("/")))
    val response = call1.execute()
    call1.cancel()

    // That connection is pooled, and it works.

## Useful tips

### How Gradle Works

We have [a series of blog](https://blog.gradle.org/how-gradle-works-1) that explains how Gradle works.
This may help you better understand and contribute to Gradle.

### Debugging Gradle

	// We can safely allow RenameFile errors up to len(er.getDisks()) - writeQuorum
	// otherwise return failure. Cleanup successful renames.
	return evalDisks(disks, errs), err
}

// PutObjectPart - reads incoming stream and internally erasure codes
// them. This call is similar to single put operation but it is part
// of the multipart transaction.
//
// Implements S3 compatible Upload Part API.

	}
	tmp := make([]byte, len(b))
	copy(tmp, b)
	h.block <- tmp
	return len(b), h.err
}

// CloseWithError will close the stream and return the specified error.
// This can be done several times, but only the first error will be sent.
// After calling this the stream should not be written to.
func (h *httpStreamResponse) CloseWithError(err error) {
	if h.done == nil {
		return
	}
	h.done <- err
