This book is written to express many years of experience of building all kinds of applications with Python, from small system scripts done in a couple of hours to very large applications written by dozens of developers over several years. It describes the best practices used by developers when working with Python. This book covers some topics that do not focus on the language itself but rather on the tools and techniques used to work with it. In other words, this book describes how an advanced Python developer works every day. www.it-

Python is widely practiced in various sectors of finance, such as banking, investment management, insurance, and even real estate, for building tools that help in financial modeling, risk management, and trading. Even big financial corporations embrace Python to build their infrastructure for position management, pricing, risk management, and trading systems.

Pandas is a third-party package for the Python programming language and, as of the printing of this book, is on version 0.20. Currently, Python has two major supported releases, versions 2.7 and 3.6. Python 3 is the future, and it is now highly recommended that all scientific computing users of Python use it, as Python 2 will no longer be supported in 2020. All examples in this book have been run and tested with pandas 0.20 on Python 3.6.

Benny Kjr Nielsen and Allan Odgaard fbenny, [email protected] February 14, 2003 The main subject of this thesis is the so-called nesting problem, which (in short) is the problem of packing arbitrary two-dimensional shapes within the boundaries of some container. The objective can vary e.g. minimizing the size of a rectangular container or maximizing the number of shapes in the container, but the core problem is to pack the shapes tightly without any overlap.

This thesis addresses the Irregular Piece Placement problem, also known as Nesting problem, while focusing on the resolution of real world instances with continuous rotations. The real world instances are considered very large instances containing many pieces with very complex outlines, where continuous rotations may be desired. The Nesting problem is presented, with a description of its characteristics, identifying the main challenges, and related problems. This is done through a literature review, considering the geometric representations and common solution approaches that are normally used, in order to identify possible paths to explore, and confirm its inherent difficulty in being efficiently tackled, specially when dealing with continuous rotations

This paper describes the Boost C++ template metaprogramming library (MPL), an extensible compile-time framework of algorithms, sequences and metafunction classes. The library brings together important abstractions from the generic and functional programming worlds to build a powerful and easy-to-use toolset which makes template metaprogramming practical enough for the real-world environments. The MPL is heavily influenced by its run-time equivalent - the Standard Template Library (STL), a part of the C++ standard library [STL94], [ISO98]. Like the STL, it defines an open conceptual and implementation framework which can serve as a foundation for future contributions in the domain. The library's fundamental concepts and idioms enable the user to focus on solutions without navigating the universe of possible ad-hoc approaches to a given metaprogramming problem, even if no actual MPL code is used. The library also provides a compile-time lambda expression facility enabling arbitrary currying and composition of class templates, a feature whose runtime counterpart is often cited as missing from the STL. This paper explains the motivation, usage, design, and implementation of the MPL with examples of its real-life applications, and offers some lessons learned about C++ template metaprogramming.
