Answer 1

See this link to craete your own comparator. You can even compare by multiple attributes or complex logic.

It works as this: cmp_to_key expects a function giving key = cmp_to_key(obj) where obj is an object to be sorted. Finally an object implementing comparator operators is returned, and can be used so you can do any custom comparisson logic.
