# This is a dictionary comprehension
# We'll see an example after this assignment!

euro_data = {
    item_id: [name, price, category, sizes]
    for item_id, name, price, category, sizes in zip(
        item_ids_list, item_names_list, euro_prices_list, item_category_list, sizes_list
    )
}

euro_data

''' 2  Calculate the Total Cost of Items

Use a list comprehension to collect them into a list. '''


sum([euro_data[key][1] for key, value in euro_data.items()])

# new_list = [expression for member in other_iterable (if condition)]
# new_dict = {key: value for key, value in other_iterable (if condition)}
