## Recapitulando

* Importe `FastAPI`.
* Crie uma instância do `app`.
* Coloque o **decorador que define a operação** (como `@app.get("/")`).
* Escreva uma **função para a operação da rota** (como `def root(): ...`) abaixo.

        override fun isExecuted(): Boolean = TODO()

        override fun isCanceled(): Boolean = TODO()

        override fun timeout(): Timeout = TODO()

        override fun clone(): Call = TODO()
      }
  }

  @Test
  fun callback() {
    val callback =
      object : Callback {
        override fun onFailure(
          call: Call,
          e: IOException,

{!../../../docs_src/python_types/tutorial002.py!}
```

That is not the same as declaring default values like would be with:

```Python
    first_name="john", last_name="doe"
```

It's a different thing.

We are using colons (`:`), not equals (`=`).

And adding type hints normally doesn't change what happens from what would happen without them.

But now, imagine you are again in the middle of creating that function, but with type hints.

  override fun isExecuted(): Boolean = error("unexpected")

  override fun isCanceled(): Boolean = error("unexpected")

  override fun timeout(): Timeout = error("unexpected")

  override fun clone(): Call = error("unexpected")

    * You can imagine that `main:app` is equivalent to a Python `import` statement like:

        ```Python
        from main import app
        ```

    * So, the colon in `main:app` would be equivalent to the Python `import` part in `from main import app`.

* `--workers`: The number of worker processes to use, each will run a Uvicorn worker, in this case, 4 workers.

   * the internal list.
