A opção `--upgrade` diz ao `pip` para atualizar os pacotes se eles já estiverem instalados.

    Por causa do passo anterior de copiar o arquivo, ele pode ser detectado pelo **cache do Docker**, esse passo também **usará o cache do Docker** quando disponível.

### Create a `SessionLocal` class

Each instance of the `SessionLocal` class will be a database session. The class itself is not a database session yet.

But once we create an instance of the `SessionLocal` class, this instance will be the actual database session.

Você também pode usá-lo para gerar código automaticamente para clientes que se comunicam com sua API. Por exemplo, aplicativos front-end, móveis ou IoT.

## Recapitulando, passo a passo

### Passo 1: importe `FastAPI`

```Python hl_lines="1"
{!../../../docs_src/first_steps/tutorial001.py!}
```

`FastAPI` é uma classe Python que fornece todas as funcionalidades para sua API.

itself, and use internally only data that doesn't depend on the resources of dependencies with `yield`.

For example, instead of using the same database session, you would create a new database session inside of the background task, and you would obtain the objects from the database using this new session. And then instead of passing the object from the database as a parameter to the background task function, you would pass the ID of that object and then obtain the object again inside the background...
