Using techniques based on the author's experience in agricultural biotechnology, this book explains to scientists how Python (an easy-to-use and powerful computer language) can help them solve biological problems. After an introduction to the principles of programming, the book discusses the Biopython package, which is useful when solving life science problems. The next section covers sophisticated tools for bioinformatics, including relational database management systems and XML. The book's last part includes commented source code for applicatons such as sequence manipulation, filtering vector contamination, calculating DNA melting temperature, parsing a genbank file, and inferring splicing sites. Appendices include instructions for installing Python and Biopython, and a Python language and style guide. Annotation ©2009 Book News, Inc., Portland, OR (booknews.com)
