 1. Imprimir todos los elementos en la consola, en lugar de solo un elemento de la lista.

+> Tendrás que iterar a lo largo de la lista entera usando un bucle `for`.
 
 ## 💡 Pista:
 
 + Si tu objetivo es imprimir cada elemento, que es una tarea repetitiva, podemos usar un bucle. Piensa, por cada item(`each_item`) de `my_list`, ¿Qué queremos? Podemos hacer la referencia a cada item usando `each_item` y ejecutar cualquier operación que queramos en cada iteración.

+
+## 💡 Hint:
 
  + If our goal is to print every item, which is a repetitive task, we can use a loop. Think, for `each_item` in `my_list`, what do we want? We can then use the namespace reference to each item by using `each_item` and perform any operations we want upon each iteration.
