This book will:Show the reader how to get started quickly: Although the Python programming language is a powerful object-oriented language, it's easy to learn, especially for programmers already familiar with C or C++. Show the reader how to write less code: Comparisons of program metrics (class counts, method counts, and so on) suggest that a program written in the Python programming language can be four times smaller than the same program written in C++. Show the reader how to write better code: The Python programming language encourages good coding practices, and automatic garbage collection helps you avoid memory leaks. Show the reader how to develop programs more quickly: The Python programming language is simpler than C++, and as such, your development time could be up to twice as fast when writing in it. Your programs will also require fewer lines of code.Chapter by chapter this book gradually builds up a practical body of code that will serve as an extensible financial engineering system in python. The book uses the Black-Scholes example to begin the building of the python package that will house the code that will be presented as the book progresses.Contents 1 Welcome to Python 1.1 Why Python? 1.1.1 Python is a high-level programming language 1.1.2 Python 'plays well with others' 1.1.3 Common misconceptions about Python 1.2 Roadmap for this book 2 First steps with Python 2.1 The Black-Scholes Formula 2.2 Modules and Packages 2.3 Unit-testing 3 Extending Python from C++ 3.1 Boost.Datetime types 3.2 Boost.MultiArray types 4 Basic Mathematical Tools 4.1 Random number generation 4.2 N(.) 4.3 Interpolation 4.3.1 Interpolation in a single dimension 4.3.2 Interpolation in multiple-dimensions 4.4 Root-finding 4.4.1 Bisection Method 4.4.2 Newton-Raphson Method 4.5 Quadrature 4.5.1 Hermite 4.5.2 Piecewise constant polynomial integration 4.6 Linear Algebra 4.6.1 Matrix Inversion 4.6.2 Singular Value Decomposition 4.6.3 Solving Tridiagonal Systems 4.6.4 Solving linear systems 4.6.5 Pseudo square root 5 Curve and surface construction 5.1 Discount Factor Curves 5.2 Caplet Volatility Curves 5.3 Intensity Curves 5.4 Swaption Volatility Skew Cube 6 Pricing using Numerical Methods 6.1 Monte-Carlo pricing framework 6.2 A lattice pricing framework 7 The Hull-White model 7.1 A component based design 7.1.1 The state 7.1.2 The cache 7.1.3 The requestor 7.1.4 The filler 7.1.5 The rollback 7.1.6 The evolve 7.2 Pricing a Bermudan 7.3 Pricing a TARN 8 Hybrid Python/C++ Pricing Systems Appendices 1 A Survey of Python Programming Tools .2 Hull-White model
