#### Un ítem aleatorio { #a-random-item }

Con `data.items()` obtenemos un <abbr title="Algo que podemos iterar con un for, como una list, set, etc.">objeto iterable</abbr> con tuplas que contienen la clave y el valor para cada elemento del diccionario.

Convertimos este objeto iterable en una `list` propiamente dicha con `list(data.items())`.

        try {
            negotiate(port, resp);
        } catch (final ConnectException | NoRouteToHostException nr) {
            // Try an alternate port if there was an issue communicating to the server
            // Only set the alternate port to the port property if it was successful
            final int altPort = port == 0 || port == DEFAULT_PORT ? 139 : DEFAULT_PORT;
            negotiate(altPort, resp);
            port = altPort;
        }

      for (i in 0 until size) {

          continue
        }

        val value = value(i)

     * We should probably not have implemented equals() at all, but given that we did, we can't
     * provide a better implementation than the input Collection, at least without dramatic changes
     * like copying it to a new Set—which might then test for element equality differently.

**Spoiler alert**: the tutorial - user guide includes:

* Declaration of **parameters** from other different places as: **headers**, **cookies**, **form fields** and **files**.
* How to set **validation constraints** as `maximum_length` or `regex`.
* A very powerful and easy to use **<abbr title="also known as components, resources, providers, services, injectables">Dependency Injection</abbr>** system.
