Sorry, there is no printed version at this point. I wanted to focus on the e-book variant first.

While this is not necessarily an argument against a printed version, note that this book works best when reading on a computer. It comes with the full source code bundle and a small utility that allows to execute all code examples interactively.

Also, it is likely that there will be updates to the book in the near future. I'm already considering to write an appendix. By exclusively providing an e-book, iterative improvements are easier to do and the readers get all updates for free.

Nevertheless, I may consider to offer a printed version later on.
