Scientific Scripting with Python
'Scientific Scripting with Python' is a great way to learn how to automate your work with Python, whether you are a scientist or not. Available on the iPhone, and via lulu.com as a paperback or PDF download, this ebook teaches you the basics of the popular Python scripting language, before delving deep into all aspects of processing data.
Python is a simple, yet powerful, programming language similar to Perl, Tcl, and Ruby. It is heavily used in scientific research, and by companies like Google.
This book places a strong emphasis on practical techniques for handling data. Although targeted specifically at scientists and engineers, anyone that needs to automate their work flow would find it useful.
Every effort has been made to make reading this text as comfortable as possible on the small iPhone screen. Text has been specially formatted to make it more readable, and pages have been made extra long, to avoid unnecessary breaks in source code examples.
An interactive table of contents has also been provided, making it easy to quickly move around in the book. This makes it suitable as a reference, even if you have no intention of reading it 'cover-to-cover'.
About the Author
--------------
Dr. Drew McCormack has been developing scientific software for 15 years on systems ranging from desktop Macs to massively-parallel supercomputers. He is a board member of MacResearch.org, a web site for Mac-using scientists, and contributes regular articles on topics ranging from Mac and iPhone application development, to Python scripting and parallel programming.
Requirements
-----------
Although this book assumes no prior knowledge of programming, some familiarity with the UNIX command line is required. Readers should be able to edit text files, and run commands in the terminal.
