It's also the same as

    [items[x] for x in [values.index(i) for i in new_values]]

Which reduces to

    [items[values.index(i)] for i in new_values]

(Although 'i' is not a good choice of variable as it represents a
value, not an index)

Anyway it doesn't work well if the 'values' list has repeated values,
e.g.

items = ['spam', 'eggs', 'wafer']
values = [3, 7, 3]
