دانلود کتاب سریع پایتون، ویرایش چهارم

Since I wrote the third edition of this book, more than five years have passed, and in that time we’ve been through some changes—including a pandemic and various crises but also the continued growth of data science and machine learning, the rise of AI-assisted code (AI everything, it seems), and of course the continued growth of Python, which is now one of the most used coding languages on the planet. I’ve been coding in Python for almost 25 years now, far longer than in any other language I’ve ever used. I’ve used Python for system administration, web applications, database management, and data analysis over those years, but most important, I’ve come to use Python just to help myself think about a problem more clearly. Based on my earlier experience, I would have expected that by now I would have been lured away by some other language that was faster, cooler, sexier, whatever. I think there are two reasons that didn’t happen. First, while other languages have come along, none has helped me do what I needed to do quite as effectively as Python. Even after all these years, the more I use Python and the more I understand it, the more I feel the quality of my programming improves and matures. The second reason I’m still around is the Python community. It’s one of the most welcoming, inclusive, active, and friendly communities I’ve seen, embracing scientists, quants, web developers, systems people, and data scientists on every continent. It’s been a joy and honor to work with members of this community, and I encourage everyone to join in. Writing this book has shown me again how time passes and things change. While we’re still on Python 3, today’s Python 3 has evolved considerably even from the Python 3.6 of the last edition of this book. Things that were never dreamed of are now features of the language, and even the old nemesis of multicore processing, the GIL, is on the verge of workable solutions. As the language has changed, so too have the ways people use Python. Although my goal has always been to keep the best bits of the previous edition, there have been a fair number of additions, deletions, and reorganizations that I hope make this edition both useful and timely. I’ve tried to keep the style clear, low-key, and also accessible to the many Python coders around the world whose first language is not English. For me, the aim of this book is to share the positive experiences I’ve gotten from coding in Python by introducing people to Python 3, the latest and, in my opinion, greatest version of Python to date. May your journey be as satisfying as mine has been.
