Get Values From A Tuple In A List In Python

x = Bookshop() x.orders = [ [1, ('5464', 4, 9.99), ('8274',18,12.99), ('9744', 9, 44.95)], [2, ('5464', 9, 9.99), ('9744', 9, 44.95)], [3, ('5464', 9, 9.99), ('88112', 11, 24.99)],

Solution 1:

To get those totals for a specific code you can do:

Code:

def get_value(orders_list, code):
    return {order[0]: o[1] * o[2] for order in orders_list
            for o in order[1:] if o[0] == code}

Test Data:

orders = [
    [1, ("5464", 4, 9.99), ("8274", 18, 12.99), ("9744", 9, 44.95)],
    [2, ("5464", 9, 9.99), ("9744", 9, 44.95)],
    [3, ("5464", 9, 9.99), ("88112", 11, 24.99)],
    [4, ("8732", 7, 11.99), ("7733", 11, 18.99), ("88112", 5, 39.95)]
]

print(get_value(orders, '5464'))

Results:

{1: 39.96, 2: 89.91, 3: 89.91}
