We all know that python is slower than compiled languages like C. But what can you do about it? Jake VanderPlas, director of research in the physical sciences for the university of Washington's eScience institute, digs into python's internals to explain how it works and what program design choices you can make to use python efficiently.
I don't get why they characterize "forgiving" as a virtue of dynamic typing.
On that specific point, they don't. The comment about "forgiving" is a separate sentence to that regarding dynamic typing. They are saying that Python in general is "forgiving".
Whether "forgiving" is a good thing or not I couldn't really say in this case, since I'm not sure in what ways the author means that Python is forgiving (and can't really think of any myself).
Well, it certainly isn't forgiving about changes of indentation. ;-)
