Very helpful for MATLAB users
This is a great book if you are familiar with Matlab programming and are moving into using python. It has been a great resource for me. I am an EE, focused on the circuits side not software, and have had to use python for a modeling program for work. I had zero exposure to Python but had used Matlab for a few years, this book really helped make the transition less painful (actually, it was somewhat fun). I recommend this book as well as the author's more introductory text: A Primer On Scientific Programming in Python. The combination of these two books, plus google, has been enough to do everything I've needed.
