I have a computer science and programming background. I want to learn Bioinformatics and am looking for a good book to start with the basics. From this review the books like "Bioinformatics Programming Using Python" are more programming oriented than biology oriented. So, is there any book out there for programmers like me who want to learn Bioinformatics?

Also, please note that I can do Python and C++. Also, I can learn Perl but that would be an extra step. I'd like if I can leverage the current programming languages I know.
