I must say I find Wesley Chun's explanations to be most understandable. I cant' exactly figure out why yet, but he has a way of explaining something, like, say, decorators, that in minimal words elucidates for me the intent behind why they are useful. That helps me understand how they work. I just finished reading the chapter on Functions for the book, I guess I was partly prompted by this thread on the newsgroup. it was a *very* quick read, I could scan quickly but gain a better understanding of the whole topic of functions in Python, including inner functions, closures, decorators, continuations, and coroutines. Talk about bang for the buck, that half hour to 45 minutes of reading new chapter in Wesley Chun's new book was the best investment of time i have made in quite a while.
I really like this book. I really, really, really like it. Ron Stephens -- http://mail.python.org/mailman/listinfo/python-list
