Adds a new item to the shopping list
:param item: Item to be added
:return:

# Add the item to the list
shopping_list.append(item)
# Notify the user that the item was added and state the number of items in the list currently
print("Added! List has {} {}".format(len(shopping_list), "items" if len(shopping_list) > 1 else "item"))
