 *Question :*
The first list contains some items, and the second list contains their value
(higher is better).

items = [apple, car, town, phone]
values = [5, 2, 7, 1]

Show how to sort the 'items' list based on the 'values' list so that you end
up with the following two lists:

items = [town, apple, car, phone]
values = [7, 5, 2, 1]

*Ans. 1*

values, items = list(zip(*sorted(zip(values,items), reverse=True)))

*Ans. 2*
new_values = sorted(values, reverse=True)
new_items = [items[x] for x in map(values.index,new_values)]

I would like to know which method is better and why?

With Regards,
Abhishek Tiwari
