Hey everyone, quick heads up regarding the Kindle version of the book:

We’re working on slimming down the generated .mobi file so that it fits into the Send-to-Kindle limit. If you’re getting an error message saying “Send-to-Kindle does not support documents over 50 MB”, that’s why.

Dan Bader RP Team on June 4, 2020

Anthony just provided me with a new build of the book that reduces the Kindle (.mobi) file size so it fits under the Send-to-Kindle limit. This new build also fixes some typos and other errata. To see the changelog & download the updated files please use the links at the top of this page. Thanks!

loumarco on June 4, 2020

Thanks a bunch.... There be learnin’ in my short-term future!

Allenite on June 4, 2020

Anthony Shaw RP Team on June 9, 2020

Hey Everyone! For those who are up to the chapter on the Grammar- Python 3.9 has got a new Parser (called the PEG) and a new grammar file. Its so new that I stuck with the existing one as up until a few weeks ago it wasn’t finished. 3.9.0 beta 2 should be out this week and I’m going to update the chapter for the new Grammar syntax so you won’t need to use -X oldparser when going through the Almost-Equal operator.

Peter Cavallaro on June 11, 2020

Awesome book, Anthony. This is an instant favourite.

I’m having trouble executing the python compiled executable file. The program fails to execute and gives this error message: error while loading shared libraries: libpython3.9.so.1.0: cannot open shared object file: No such file or directory. What did I do wrong?

I believe I folowed the exact steps in the chapter. I’ve tried executing, with the exact same error message, in both mac os big sur and ubuntu running on wsl2. Please help.

Dan Bader RP Team on Jan. 25, 2021

I’ve got some great news to share: We’re officially ending the Early Access phase for the book today :) This update is huge, with a full proofreading pass, minor and major layout improvements to pretty much every chapter. So go ahead and download your updated book files on this page under the Description tab.

Happy Pythoning!

Hi,

stupid question: After buying the book, will I receive a hard copy or is the book only an ebook?

Dan Bader RP Team on Jan. 30, 2021

We are in the process of getting a paperback version ready for publishing. When the paperback version is released it will be a separate purchase from Amazon or your favorite local book store. The release date we’re aiming for with the paperback is later this year. Pricing for the hard copy will depend on our printing costs and we will try to have some kind of discount available for customers who purchased the digital version. So stay tuned for further announcements on the RP email newsletter!
