There is a lot to like about this book:
- The authors clearly know their stuff, and in detail. Everything is demonstrated with code.
- The individual tips are well-organized, with a statement of the problem, solution, and discussion. I found the format easy to skim (for stuff I already basically knew), and easy to dive in where necessary.
- The authors provide lots of links to additional resources.
- internal iterators
- Duck Typing
- Functional Programming
