#### 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())`.
