When you’re new to Python, it can be tough to understand where and how to use its many language features. There’s a dizzying array of libraries, and it’s challenging to fit everything together. The Well-Grounded Python Developer builds on Python skills you’ve learned in isolation and shows you how to unify them into a meaningful whole. As you work through this practical guide, you’ll discover how all the bits of the Python ecosystem connect as you build and modify a typical web server application.
about the technology
Python is the perfect language for beginning programmers. It is easy to learn, with tons of helpful libraries and tools. Better still, it doesn’t run out of steam when you want to create more advanced applications for web development or Machine Learning. Once you’ve mastered the syntax of simple Python scripts, it can be a challenge to progress to more ambitious projects. This book helps you on that path.
about the book
The Well-Grounded Python Developer teaches you how to write real software in Python by building on the basic language skills you already have. Veteran developer Doug Farrell helps you see the big picture you can create out of small pieces, introducing concepts like modular construction, APIs, and the design of a basic web server. Throughout the book, you’ll practice your skills by building a blogging platform—the kind of web app that’s in high demand by modern businesses. When you’re finished, you’ll have gone from having a basic understanding of Python's syntax, grammar, and libraries to using them as the tools of a professional software developer.
