My solution, I know the 'zip' version is more elegant, this is just for
fun:)

>>> items = ['apple', 'car', 'town', 'phone']
>>> values = [5, 2, 7, 1]
>>> new_values = sorted(values, reverse = True)
>>> new_items = [items[x] for x in [i for i in map(values.index,
new_values)]]
>>> print(new_values)
[7, 5, 2, 1]
>>> print(new_items)
['town', 'apple', 'car', 'phone']
>>>

cheers!
