I could keep a list here, but it’s really easier if you go to Jon Peirce on Google Scholar
Building Experiments in PsychoPy (Peirce and MacAskill) is due for release in May 2018 with Sage Publishing. This book is suitable as a textbook to support undergraduate lab classes or as a reference manual for experienced researchers, including those using neuroimaging, psychophysics and eye-trackin techniques. As the name suggests, this really focusses on the graphical Builder interface although we do introduce Python programming, increasingly through the book, to support more advanced studies.
Programming Experiments in Python, is hopefully going to be available in November 2018, also with Sage Publishing, covering the programming interface.
