Answer 1

Explanation:

gems_list = ["Emerald", "Ivory", "Jasper", "Ruby", "Garnet"]

price_list = [1760, 2119, 1599, 3920, 3999]

reqd_gems = ["Ivory", "Emerald", "Garnet"]

reqd_quantity = [3, 2, 5]

quantity_dict = dict(zip(reqd_gems, reqd_quantity))

price_dict = dict(zip(gems_list, price_list))

print("Item", "Quantity", "Unit_price", "Total_price")

for k, v in quantity_dict.items():

print(k, v, price_dict[k], price_dict[k] * v)

print("Grand_total", sum([price_dict[k] * v for k, v in quantity_dict.items()]))
