Once you've mastered the basics of Python, how do you skill up to the top 1%? How do you focus your learning time on topics that yield the most benefit for production engineering and data teams—without getting distracted by info of little real-world use? This book answers these questions and more.Based on author Aaron Maxwell's software engineering career in Silicon Valley, this unique book focuses on the Python first principles that act to accelerate everything else: the 5% of programming knowledge that makes the remaining 95% fall like dominos. It's also this knowledge that helps you become an exceptional Python programmer, fast.Learn how to think like a Pythonista: explore advanced Pythonic thinkingCreate lists, dicts, and other data structures using a high-level, readable, and maintainable syntaxExplore higher-order function abstractions that form the basis of Python librariesExamine Python's metaprogramming tool for priceless patterns of code reuseMaster Python's error model and learn how to leverage it in your own codeLearn the more potent and advanced tools of Python's object systemTake a deep dive into Python's automated testing and TDDLearn how Python logging helps you troubleshoot and debug more quicklyAbout the AuthorAaron Maxwell is a software engineer and Pythonista. Through a decade working in Silicon Valley engineering teams, including two Unicorns, he has gained strong production experience in backend engineering at scale; data science and machine learning; test automation infrastructure; DevOps and SRE; cloud infrastructure; marketing automation; and much more. He codes in a variety of languages, including plenty of Python. Aaron then pivoted to training, developing an innovative curriculum for intermediate and advanced Python, which he has taught to over 10,000 technology professionals worldwide-in nearly every engineering domain, country, and culture.
