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.

		}
		if len(items) > 0 {
			operands = append(operands, items)
			if colon >= 0 && len(operands) == colon+2 {
				// AX:DX becomes DX, AX.
				operands[colon], operands[colon+1] = operands[colon+1], operands[colon]
				colon = -1
			}
		} else if len(operands) > 0 || tok == ',' || colon >= 0 {
			// Had a separator with nothing after.
			p.errorf("missing operand")
		}
	}

  // verb=attest.
  //
  // If signerName is not empty, then the ClusterTrustBundle object must be
  // named with the signer name as a prefix (translating slashes to colons).
  // For example, for the signer name `example.com/foo`, valid
  // ClusterTrustBundle object names include `example.com:foo:abc` and
  // `example.com:foo:v1`.

    * 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.

	for scanner.Scan() {
		token := scanner.Text()
		substrings := strings.SplitN(token, ":", 3)
		if len(substrings) < 3 {
			return nil, fmt.Errorf("cgroup entry contains %v colons, but expected at least 2 colons: %q", len(substrings), token)
		}
		cgroups = append(cgroups, Cgroup{
			HierarchyID:    substrings[0],
			ControllerList: substrings[1],
			GroupPath:      substrings[2],
		})
	}

        return data
    ```

    Note that for OAuth2 the scope `items:read` is a single scope in an opaque string.
    You could have custom internal logic to separate it by colon caracters (`:`) or
    similar, and get the two parts `items` and `read`. Many applications do that to
    group and organize permissions, you could do it as well in your application, just

{!../../../docs_src/python_types/tutorial006.py!}
```

Declare a variável com a mesma sintaxe de dois pontos (`:`).

Como o tipo, coloque a `List`.

Como a lista é um tipo que contém alguns tipos internos, você os coloca entre colchetes:

```Python hl_lines="4"
{!../../../docs_src/python_types/tutorial006.py!}
```

!!! tip "Dica"
    Esses tipos internos entre colchetes são chamados de "parâmetros de tipo".

* a rota `/`
* usando o  <abbr title="o método HTTP GET">operador <code>get</code></abbr>

!!! info "`@decorador`"
    Essa sintaxe `@alguma_coisa` em Python é chamada de "decorador".

    Você o coloca em cima de uma função. Como um chapéu decorativo (acho que é daí que vem o termo).

    Um "decorador" pega a função abaixo e faz algo com ela.

	urlStr := uu.String()
	u, err := url.Parse(urlStr)
	if err != nil {
		// Mark offline, with no reconnection attempts.
		connected = int32(offline)
		err = &url.Error{URL: urlStr, Err: err}
	}
	// The host's colon:port should be normalized. See Issue 14836.
	u.Host = removeEmptyPort(u.Host)

	// Transport is exactly same as Go default in https://golang.org/pkg/net/http/#RoundTripper
	// except custom DialContext and TLSClientConfig.

!!! check "**FastAPI** usa isso para"
    Controlar toda a validação de dados, serialização de dados e modelo de documentação automática (baseado no JSON Schema).

    **FastAPI** então pega dados do JSON Schema e coloca eles no OpenAPI, à parte de todas as outras coisas que ele faz.
