Because artificial intelligence generates code in seconds today software engineering matters more than ever.
Successful software developers must document system structure, data flow, security boundaries to manage long-term maintainability.
Without a clear, thoughtful design framework, AI simply helps teams build a faster, more complex maze of technical debt.

About the Book
From managing requirements, to learning how to choose between the best projects, a successful software developer needs to know a lot more than merely how to ‘write code.’ Tenured software professionals know that designing, testing, and delivering software for ourselves and others is what real-world, modern software development is all about.
Because modern software developers need to understand how to create software from requirements & design specifications, when Pythoneers started asking me for more practice exercises, I thought that I would define those projects using the type of documentation professional software developers are most likely to encounter.
From creating a simple “Hex Dumper” and / or “Big Banner” tool, to creating and reporting on dictionaries loaded with data, the exercises in this book are designed to provide a gentle, evolutionary, real-world educational experience. Students will be exploring everything from using Python’s built-in functions, to practicing common research, maintenance, as well as software re-factoring activities.
p.s. Be it in-the-cloud or in-person, our Python training has been taught to thousands of new software developers. If you have never programmed before then you should consider taking the FREE Python 1000: The Python Primer at Soft9000.com as well. 🎓
