Appendix A: Pedal to the Metal: Accelerating Python. The main focus of this book is asymptotic efficiency—making 
your programs scale well with problem size. However, in some cases, that may not be enough. This appendix gives you 
some pointers to tools that can make your Python programs go faster. Sometimes a lot (as in hundreds of times) faster.
Appendix B: List of Problems and Algorithms. This appendix gives you an overview of the algorithmic problems and 
algorithms discussed in the book, with some extra information to help you select the right algorithm for the problem 
at hand.
