Isso não é o mesmo que declarar valores padrão como seria com:

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

É uma coisa diferente.

Estamos usando dois pontos (`:`), não sinal de igual (`=`).

E adicionar type hints normalmente não muda o que acontece do que aconteceria sem eles.

Mas agora, imagine que você está novamente no meio da criação dessa função, mas com type hints.

				t.Errorf("Test %d: Parsed Signature field mismatch: Expected \"%s\", got \"%s\"", i+1, testCase.expectedAuthField.Signature, parsedAuthField.Signature)
			}

			// validating the extracted signed headers.
			if strings.Join(testCase.expectedAuthField.SignedHeaders, ",") != strings.Join(parsedAuthField.SignedHeaders, ",") {
