Sorting records with key functions

Sort records by any field with key=lambda, reverse the order, break ties with tuple keys, and mix ascending and descending.

You will be able to

• Sort with sorted(..., key=...) using a lambda that picks the sort value
• Use reverse=True and explain how sorting is stable
• Sort by several fields at once with a tuple key
• Mix ascending and descending order by negating numeric keys
