Copes Flavio. The Python Handbook

Independently published, Copes Flavio, 2023. — 93 p.Python is eating the programming world. It is growing in popularity and usage in ways that are pretty much unprecedented in the history of computers. There is a huge variety of scenarios that Python excels in. Shell scripting, task automation, and Web development are just some basic examples. Python is the language of choice for data analysis and machine learning, but it can also adapt to create games and work with embedded devices. Most importantly, it's the language of choice for introductory computer science courses in universities all around the world. Many students learn Python as their first programming language. Many are learning it right now, and many will learn it in the future. And for many of them, Python will be the only programming language they need. Thanks to this unique position, Python is likely going to grow even more in the future.The language is simple and expressive, and it's quite straightforward. The ecosystem is huge. There seems to be a library for everything you can imagine. Python is a high-level programming language suitable for beginners thanks to its intuitive syntax, it's huge community, and its vibrant ecosystem. It is also appreciated by professionals across many different fields. Technically speaking it is an interpreted language that does not have an intermediate compilation phase like a compiled language, for example, C or Java. Like many interpreted languages, it is dynamically typed, which means that you do not have to indicate the types of the variables you use, and variables are not tied to a specific type. This has pros and cons. In particular, we can mention that you write programs faster, but on the other hand, you have less help from the tools to prevent possible bugs and you will find out about some kinds of issues only by executing the program at runtime. Python supports a wide variety of different programming paradigms, including procedural programming, object-oriented programming, and functional programming. It's flexible enough to adapt to a lot of different needs.Starting with Python is very easy. All you need is to install the official package from python.org, for Windows, macOS, or Linux, and you're ready to go. If you are new to programming, in the following posts I will guide you to go from zero to becoming a Python programmer. And even if you are currently a programmer specialized in another language, Python is a language worth knowing because I think we're just at the start. Lower-level languages like C++ and Rust might be great for expert programmers, but daunting to begin, and they take a long time to master. Python, on the other hand, is a programming language for programmers, of course, but also for non-programmers. The students, the people doing their day job with Excel, the scientists. The language everyone interested in coding should learn first.
