The agile development movement represents the latest advances in tools and techniques intended to boost developer productivity. This movement is capturing the attention of developers of all disciplines, and is particularly prevalent in cutting-edge open source communities such as Python and Ruby. This is the first book to apply these sought after principles to Python developers, introducing both the tools and techniques built and supported by the Python community. Authored by Jeff Younker, a well-known member of Pythons agile community who is perhaps best known for his creation of a popular Python testing framework, this book is sure to be a hit among readers who may have reached their limits of knowledge regarding the Python language, yet are seeking to improve their understanding of how sound processes can boost productivity to unparalleled heights.
