Hello and welcome to Python Basics: A Practical Introduction to Python 3. I hope you are ready to learn why so many professional and hobbyist developers are drawn to Python and how you can begin using it on your projects, small and large, right away. This book is targeted at beginners who either know a little programming but not the Python language and ecosystem, as well as complete beginners. If you don’t have a Computer Science degree, don’t worry. Fletcher, David, Dan, and Joanna will guide you through the important computing concepts while teaching you the Python basics, and just as importantly, skipping the unnecessary details at first. Python Is a Full-Spectrum Language When learning a new programming language, you don’t yet have the experience to judge how well it will serve you in the long run. If you are considering Python, let me assure you that this is a good choice. One key reason is that Python is a full spectrum language. What do I mean by this? Some languages are very good for beginners. They hold your hand and make programming super easy.

We can go to the extreme and look at visual languages such as Scratch. Here you get blocks that represent programming concepts, like variables, loops, method calls, and so on, and you drag and drop them on a visual surface. Scratch may be easy to get started with for simple programs. But you cannot build professional applications with it. Name one Fortune 500 company that powers its core business logic with Scratch. Came up empty? Me too—because that would be insanity. Other languages are incredibly powerful for expert developers. The most popular one in this category is likely C++ and its close relative C. Whatever web browser you used today was likely written in C or C++. Your operating system running that browser was also very likely built with C/C++. Your favorite first-person shooter or strategy video game? You nailed it: C/C++. You can do amazing things with these languages. But they are wholly unwelcoming to newcomers looking for a gentle introduction. Both Scratch and C++ are decidedly not what I would call full spectrum languages. In the Scratch level, it’s easy to start but you have to switch to a “real” language to build real applications. Conversely, you can build real apps with C++, yet there is no gentle on-ramp. You dive head first into all the complexity of that language which exists to support these rich applications.
