Book Description

Powerful, flexible, and easy to use, Python is an ideal language for building software tools and applications for life science research and development. This unique book shows you how to program with Python, using code examples taken directly from bioinformatics. In a short time, you’ll be using sophisticated techniques and Python modules that are particularly effective for bioinformatics programming.

Bioinformatics Programming Using Python is perfect for anyone involved with bioinformatics — researchers, support staff, students, and software developers interested in writing bioinformatics applications. You’ll find it useful whether you already use Python, write code in another language, or have no programming experience at all. It’s an excellent self-instruction tool, as well as a handy reference when facing the challenges of real-life programming tasks.

• Become familiar with Python’s fundamentals, including ways to develop simple applications
• Learn how to use Python modules for pattern matching, structured text processing, online data retrieval, and database access
• Discover generalized patterns that cover a large proportion of how Python code is used in bioinformatics
• Learn how to apply the principles and techniques of object-oriented programming
• Benefit from the “tips and traps” section in each chapter Download Now »

Book Description

Providing appealing plots and graphs is an essential part of various fields such as scientific research, data analysis, and so on. Matplotlib, the Python 2D plotting library, is used to produce publication-quality figures in a variety of hardcopy formats and interactive environments across platforms. This book explains creating various plots, histograms, power spectra, bar charts, error charts, scatter-plots and much more using the powerful Matplotlib library to get impressive out-of-the-box results.

This book gives you a comprehensive tour of the key features of the Matplotlib Python 2D plotting library, right from the simplest concepts to the most advanced topics. You will discover how easy it is to produce professional-quality plots when you have this book to hand.

The book introduces the library in steps. First come the basics: introducing what the library is, its important prerequisites (and terminology), installing and configuring Matplotlib, and going through simple plots such as lines, grids, axes, and charts. Then we start with some introductory examples, and move ahead by discussing the various programming styles that Matplotlib allows, and several key features.

Further, the book presents an important section on embedding applications. You will be introduced to three of the best known GUI libraries–GTK+, Qt, and wxWidgets–and presented with the steps to implement to include Matplotlib in an application written using each of them. You will learn through an incremental approach: from a simple example that presents the peculiarities of the GUI library, to more complex ones, using GUI designer tools. Download Now »

Book Description

There are many more people who want to study programming other than aspiring computer scientists with a passing grade in advanced calculus. This guide appeals to your intelligence and ability to solve practical problems, while gently teaching the most recent revision of the programming language Python.

You can learn solid software design skills and accomplish practical programming tasks, like extending applications and automating everyday processes, even if you have no programming experience at all. Authors Tim Hall and J–P Stacey use everyday language to decode programming jargon and teach Python 3 to the absolute beginner.
What you’ll learn

• Cultivate a problem–solving approach and acquire software design skills.
• Learn how to create your own software from simple “Hello World” type programs to stand–alone windowed applications.
• Document while programming, program while documenting.
• Decode programmers’ jargon.
• Master the Python 3 programming language. Download Now »

Book Description

With refactoring, programmers can transform even the most chaotic software into well-designed systems that are far easier to evolve and maintain. What’s more, they can do it one step at a time, through a series of simple, proven steps. Now, there’s an authoritative and extensively updated version of Martin Fowler’s classic refactoring book that utilizes Ruby examples and idioms throughout–not code adapted from Java or any other environment.

The authors introduce a detailed catalog of more than 70 proven Ruby refactorings, with specific guidance on when to apply each of them, step-by-step instructions for using them, and example code illustrating how they work. Many of the authors’ refactorings use powerful Ruby-specific features, and all code samples are available for download.
Leveraging Fowler’s original concepts, the authors show how to perform refactoring in a controlled, efficient, incremental manner, so you methodically improve your code’s structure without introducing new bugs. Whatever your role in writing or maintaining Ruby code, this book will be an indispensable resource.

This book will help you

• Understand the core principles of refactoring and the reasons for doing it
• Recognize “bad smells” in your Ruby code
• Rework bad designs into well-designed code, one step at a time Download Now »
