Full Review


Kay’s verdict: I thought it was a good book. It takes a very pragmatic view of what someone might need to know if they’re primarily interested in data access and need a bit of Python to get things working.

It’s not a book I would recommend for learning to program, but there’s still a lot you can do if you know how to write (or modify) a little bit of code so you can use NumPy or Pandas.

This month sees the publication of the second revised edition of Programmer’s Python: Everything is an Object in which Mike James reveals how Python has a unique and unifying approach when it comes to classes and objects. This is the first in a series of intermediate level titles for the programmer who wants to understand what makes Python special and sets it apart from other programming languages, hence the tagline “Something Completely Different – which is, of course , a reference to the television and film brand Monty Python that inspired Guido Van Rossum to name his new language. The topic is basically anything to do with how Python implements objects. say, in order of sophistication, metaclass; class; object; attribute; and all the other features like functions, methods, and the many “magic methods” that Python uses to make everything work.

This is the second of that something completely different titles and explores how data is handled in a distinctly Pythonic way. What we have in Python are very usable and very extensible data objects. From integers with unlimited precision, called bignums, to choosing a list to act as the array, to having the dictionary available as a built-in data type, Python behaves differently from other languages ​​and this book is what you need to help you get the most out of these special features. There are also comprehensive chapters on Boolean logic, dates and times, regular expressions, and bit manipulation.

Mike James is currently working on the third book in the series, Programmer’s Python: Asynchronous which not only covers the latest asyncio in depth, but has everything you need to know about the many approaches to asynchrony provided by Python – threads, processes, futures, tasks, schedulers. This is the book you need to understand all the options, trade-offs and pitfalls.

These books are not intended for complete beginners and some familiarity with object-oriented programming and Python is assumed, with the first chapter providing a quick recap. They also share an appendix on using Visual Studio Code from Python.

Programmers think differently from non-programmers, they see and solve problems in a way the rest of the world doesn’t. In this book, Mike James takes programming concepts and explains what the skill entails and how a programmer goes about it. In each case, Mike examines how we convert a dynamic process into static text that can be understood by other programmers and put into action by a computer. If you’re a programmer, its intention is to give you a better understanding of what you’re doing so that you enjoy it even more.
