Python for Developers

Dynamic languages were seen in the past only as scripting languages, used to automate small tasks, but with the passing of time, they grew, matured and conquered their place in the market, to the point of calling the attention of the major providers of technology.

Several factors contributed to this change, such as the internet, open source software and agile development methodologies. The internet has enabled the sharing of information in a way unprecedented in history, which made possible the growth of open source software. Dynamic languages are usually open source and share the same features and in some cases, the same goals.

Among the dynamic languages, Python stands out as one of the most popular and powerful. There is a lively community of language users in the world, and this is reflected in active mailing lists and many tools available in open source.

Learning a new programming language means learning to think differently. And learn a dynamic language represents a paradigm shift even harder for those people who have spent years developing in static languages.

The e-book "Python para Desenvolvedores" ("Python for Developers") aimed to fill a gap, which was the lack of free courseware in Portuguese about the Python programming language. The work was adopted as a support material for several universities in Brazil, served as a reference for academic papers and has been downloaded over 100,000 times from its official website.

This e-book was originally written in Portuguese and was translated by a small group of volunteers who do not speak English natively, so we ask for help from those who know better the English language, to refine the work, which we believe is a meaningful contribution to the Python users around the world.

The chapters below were rendered through nbviewer in real time. They are read-only. To change any of the content, simply clone this project in Github.

This part deals with the basics of Python programming language, including syntax, types, control structures, functions, and documentation.

• Chapter 1: Introduction
• Chapter 2: Syntax
• Chapter 3: Control Flow
• Chapter 4: Loops
• Chapter 5: Types
• Chapter 6: Functions
• Chapter 7: Documentation
• Exercises I

This part is about modules and packages, highlighting some of the most important ones that are present in standard library of the language, installation of third-party libraries, exceptions and introspection.

• Chapter 8: Modules
• Chapter 9: Scope of names
• Chapter 10: Packages
• Chapter 11: Standard library
• Chapter 12: Third party libraries
• Chapter 13: Exceptions
• Chapter 14: Introspection
• Exercises II

This part is divided into two topics: generators, an increasingly present technology in the language, and functional programming.

• Chapter 15: Generators

I would like to thank my wife and my parents, for their patience during the creation of this work.

Besides them, I would like to thank everyone who supported and helped to publicize the book.

Luiz Eduardo Borges is an engineer and systems analyst, a graduate degree in Computer Graphics by State University of Rio de Janeiro (UERJ). He has been working for over two decades in computer science under various ways.

This book can be read in two different ways:

1. The first way is the most interactive of all. Here you have to clone the repository of the book to download all files .ipynb to your local machine. If you have IPython installed, you can then view all the chapters in your browser and run the code examples. This is one of the best ways to maximize your learning, but some dependencies must be installed on a machine.
2. The second way is to use the site nbviewer which presents the IPython Notebook right in your browser. The content is updated according to the repository updates. To access the chapters, use the links on the Content section above.
