As a disclaimer, there have been a number of different libraries that I researched while writing this book. However, due to concerns of brevity, I've had to cap the number of libraries that I could cover within each chapter.
It would be remiss of me to not present to you some of the excellent resources currently available that present far more in-depth coverage of some of the topics I've unfortunately not been able to expand upon. I also feel that it's worthwhile knowing what further material is available that will continue to expand your knowledge of software engineering with Python.
